So I designed a process on my own. This demo shows how to migrate a CI/CD structure for an existing multi-component application from a discontinued [Atlassian Bamboo Server](https://www.atlassian.com/migration/assess/journey-to-cloud) to [GitLab CI/CD](https://docs.gitlab.com/ee/index.html) (Community Edition).\n\nThe accompanying repository is https://gitlab.com/iLychevAD/ci-cd-for-a-multi-component-app.\n\nIn this first part of a two-part series, you will find a description of the current state of affairs - i.e., how the CI/CD has been organized within Bamboo Server, how the Bamboo Build and Deploy plans are designed for bootstrapping infrastructure and deploying the components of the application, and the architecture of the application itself.\n\nAnd in part two, we'll take a deeper look at the virtues of `GitLab CI/CD`.\n\n## Initial state\n\n(Note: This is not a description of some particular project but more a kind of compilation of several projects I worked on.)\n\nThe application solution allows the client to fulfill a particular business purpose (the nature of which is not relevant here and thus not specified) and consists of more than 50 discrete components (further referred to as `applications` or just `apps` or `components`). I refrain from calling them microservices as each of them looks more like a full-fledged application communicating with other siblings using REST API and messages in Kafka topics. Some of them expose a web UI to external or internal users and some are just utility parts serving the needs of other components or performing internal operations, etc.\n\nCode for each app is stored in its own Git repository (further just `repo`). So, a `multi-repo` approach is used for them. Each app may be written in different languages and packaged as one or several OCI-images for deployment.\n\nEach app repo looks like:\n```text\n📦 \u003Csome-app-git-repo>\n ┣ 📂src \u003C-- application source code\n ┣ 📂docker-compose\n ┃ ┗ 📜docker-compose.yml \u003C-- analogue of K8s manifests\n ┗ 📜Dockerfile \u003C-- conventionally, \"Dockerfile\" name is used for OCI image specification file\n\n```\n\nFor running the applications, the client uses an outdated orchestration system (one from pre-Kubernetes epoch). So each app repo contains a Docker-compose compatible file describing deployment directives for that outdated orchestration system (in essence, similar to Kubernetes Deployment manifests).\n\nFor all of the build and deploy activities Atlassian Bamboo Server is used.\n\nSome details for those not familiar with the Bamboo Server - in an opinionated manner it explicitly separates so-called `build` pipelines and `deployment` pipelines. The former are supposed to build application code and produce some artifacts for further deployment (in our case those artifacts are OCI images uploaded to OCI registry and docker-compose.yml files referring to those images). The latter ones are supposed to take some particular set of artifacts and apply them to some particular `environment`. An `environment` (referred to `env` in the future for brevity) here is just an abstract deployment target characterized by a set of environment variables attached to it and exposed to the apps deployed into it. In reality, an `env` is implemented as a set of resources (virtual machines, databases, object storage locations, etc.) required by the applications.\n\nIn Bamboo, one `build` pipeline usually corresponds to one `deployment` pipeline so when the latter is started it just takes the artifacts from the attached `build` pipeline as input.\n\nThe client uses a `production` env, `preproduction` env, and numerous (up to several hundreds) so-called `staging` (short-lived) envs where different development teams and software engineers can test various combinations of the apps (here we assume that they have ~80-100 distinguish components of the application solution and several hundreds of software developers which gives a lot of possible combinations and requires so many `staging` envs).\n\nRoughly, a configuration of a `deploy` pipeline consists of a specification of the source artifacts (which are provided by the attached `build` pipeline as described earlier) and a specification of the set of envs where those artifacts (effectively, an application) can be deployed to.\n\nCurrent installation uses sophisticated dynamic generation of envs set for each app deployment pipeline. Roughly speaking, they have a central configuration file with the list of all existing envs where for each env a list of apps allowed to be deployed to it is denoted. Each time the file is modified (i.e., an env is created or deleted), the deployment pipelines are automatically being updated so as in the result each of them contains a list of envs corresponding for each app. You will have more idea about this aspect when you have looked at the implementation section later.\n\nIn the Bamboo UI this looks like:\n\n![envs_list_on_build_result_page](https://about.gitlab.com/images/blogimages/migration-from-atlassian-bamboo-server-to-gitlab-ci/envs_list_on_build_result_page.png)\n\nHere you can see an application build result page where on the right-hand side under the `Included in deployment project` title you can see a list of envs into which you can deploy the application. (Keep in mind that besides `build` and `deployment` pipelines, the Bamboo also uses a notion of `releases` - this is just some kind of an intermediate entity that should be created out of a build result to make it possible to deploy that build into some env). The `cloud-with-upwards-arrow` button in the `Actions` column starts a corresponding `deploy` pipeline with automatically passing the link to a build result (in a form of a `release` entity in Bamboo terminology) and the name of the env next to which the button has been clicked (the procedure of how a list of envs is created for a `deploy` pipe is described above).\n\nA concept of a `release` is specific to Bamboo Server, though it provides some amenities. For example, on the Release details page you can see a list of envs where a release has been deployed to. On the `Commits` tab you can backtrack a release to the application code in a SVC. And the `Issues` tab shows attached Jira tickets.\n\n![bamboo_release_details](https://about.gitlab.com/images/blogimages/migration-from-atlassian-bamboo-server-to-gitlab-ci/bamboo_release_details.png)\nRelease details page\n\n\nAn env details page also enumerates releases history for this env (in scope of one particular application though as an env is specified for each deployment pipeline individually):\n\n![bamboo_env_details](https://about.gitlab.com/images/blogimages/migration-from-atlassian-bamboo-server-to-gitlab-ci/bamboo_env_details.png)\nEnv details page\n\n\nAnd upon clicking the `cloud-with-upwards-arrow` button the Bamboo shows diff of Jira tickets and commits in respect to the previous `release` (only if both releases are made from artifacts from the same Git branch):\n\n![deploy_launch_page](https://about.gitlab.com/images/blogimages/migration-from-atlassian-bamboo-server-to-gitlab-ci/deploy_launch_page.png)\nDeploy launch page\n\n\nSo, in general, the current path from source control to an env for each app looks like:\n\n![svc_to_env_path](https://about.gitlab.com/images/blogimages/migration-from-atlassian-bamboo-server-to-gitlab-ci/svc_to_env_path.png)\n\nThe Build plans are triggered automatically upon Git commits or Git tags. Most of the Deployment plans are started by the project members manually when needed. Each Deploy plan contains a step that checks if a user who started the plan has permissions to deploy into an env (for example, only members of the team which owns an env are allowed to deploy to that env and the deployment to the production env is allowed only for a set of eligible project members).\n\n## The task\n\nThe task is to migrate the aforementioned design from Bamboo Server to `GitLab` while keeping a similar deployment scheme (leveraging GitLab's `Environments` feature).\n\nAlso the following should be considered:\n\n - team members (software engineers, quality assurance specialists) are supposed to be able to manage environments on their own in a user-friendly self-service manner.\n - there should not be any discrepancy in IaC for different environments (per `12-factor apps` best practices), i.e. for any kind of an environment, be it a development or production one, the same set of IaC (here - Terraform files) should be used.\n  - the core ideas and workflows established in the previous situation (implemented with Atlassian Bamboo) should be kept to make the migration smoother for the members of the projects (also sometimes referred to as just users).\n\n## Implementation\n\n### Implementation's GitLab groups\\projects structure\n\n```text\n📦 \u003CGitLab root group>\n ┣ 📂 apps GitLab group\n ┃ ┣ 📃 app1 GitLab project\n ┃ ┣  ...\n ┃ ┗ 📃 appN GitLab project\n ┣ 📂 ci GitLab group\n ┃ ┣ 📃 library GitLab project\n ┃ ┗ 📃 oci-registry GitLab project\n ┗ 📂 infra GitLab group\n  ┣ 📃 environment-blueprints GitLab project\n  ┣ 📃 environment-set GitLab project\n  ┗ 📃 k8s-gitops GitLab project\n\n```\n\n*Description*:\n\nThe most important content is in the `ci/library` repo (the shared ci configs) and `environment-set` repo. The other repos don't require much attention: The `k8s-gitops` purpose is not implemented and the repo is empty, the `apps` group just imitates source code for some apps, and the `ci/oci-registry` serves a role of an OCI registry for the solution.\n\nThe `apps` GitLab group merely contains the apps source code per se. Each GitLab project in this group corresponds to one app. Each app repo is expected to contain the source code itself (in the `src` directory for example), a `k8s` directory with k8s manifests, and an OCI image specification file (traditionally often called `Dockerfile`).\n\nThe `ci` GitLab group contains the `ci/library` project that holds shared `.gitlab-ci.yaml` files used by other projects (in a manner similar to Jenkins' shared libraries) and the `ci/oci-registry` serves as an OCI-image registry for various images used by the demo project (it also contains a Git repository with gitlab-ci files to build some utility images with tools used in various pipelines). For simplicity, the latter stores all the images throughout all the projects of the demo, though it's clearly not the best choice for a real-life situation when different sets of images of a set of separate projects/registries should be created.\n\nThe `infra` group holds applications infrastructure creation related Git repositories:\n\nThe `infra/k8s-gitops` is mostly irrelevant to the topic of this demo. In this demo it's presumed that Kubernetes is used as a computation workload platform and when a k8s cluster is created for an environment all the k8s manifests are supposed to be put into this repo (where each branch corresponds to a single environment) to be consumed by a GitOps tool installed into the cluster.\n\nThe `infra/environment-blueprints` holds parametrized IaC templates describing all the resources required for a full-fleged environment. In this example, the Terraform is used as an IaC tool though the principles are similar for its analogs (CloudFormation, for instance). The blueprints are parametrized in such manner that in the defaults values they hold some sensible values (most likely set to different values depending on the kind of a environment they were used to bootstrap - for example, a production env and everything else). It's implied that there might coexist several versions of the blueprints (implemented by using Git branches or Git tags) so each environment (see the next paragraph about `infra/environment-set`) can explicitly specify which version it wants to use (in case of using Terraform by specifying Git reference in the module's `source` field).\n\nHere I would like once again to highlight a digression from the best practices. For simplicity in the `infra/environment-blueprints` repo all the parts of an environment are combined into one single Terraform module (or a workspace, or a Stack in CloudFormation's terminology). In that way all the resources are always updated or changed within a single `terraform apply` command, which is cumbersome for large infrastructures containing a lot of resources. For larger infrastructures it would be more manageable to split into disparate Terraform modules (or CloudFormation Stacks, or Azure ARM Resource Groups) and thus make it possible for the infrastructure to be changed/updated in parts according to which exact components of it have changed. This might raise another question - how to manage dependencies in between such parts if they are present? For that, we would use some kind of an external (in respect to the IaC tool itself) orchestration tool like AWS Step Functions... or even GitLab's DAG feature!\n\nFinally, the `infra/environment-set` project represents an actual expected state of resources for each environment (a branch corresponds to an environment). See the README.md file in the Git repo for details. In short, each branch here is meant to contain a `main.tf` file referring to some version of the blueprints in the `infra/environment-blueprints` project, a set of Terraform files with overrides for any default variables set in the blueprints modules and other utility files like with a list of users allowed to deploy to the environment (such a list is to be checked by the deployments job in the apps projects).\n\n### **Important!**\n\nWhile looking at the implementation keep im mind that this solution deliberately omits some crucial aspects of any project infrastructure like security or monitoring, just for the sake of keeping this solution manageable and comprehensible. Implementing security and monitoring aspects would make the solution cumbersome and much longer to prepare. That is also true for the `k8s-gitops` repository - it's implied that in a real-life solution this would actively participate in the deployment process and hold Kubernetes clusters state in a GitOps approach but currently, this repo is just a placeholder. In the practical guide later you will see a description of the process of controlling environments using different branches in the `infra/environment-set` project. Ideally, such a workflow should use Merge Requests though for simplicity this implementation skips using MRs.\n\nAnother important thing that's possible not clear in this solution is configuration management, i.e. how configuration settings unique to each environment are provided to the applications inside an environment. Well, given that our applications run within Kubernetes cluster and that the cluster state is placed into a dedicated repo (`k8s-gitops` in our case), the configuration settings situation is simple - for each app the Terraform files in the `infra/environment-blueprints` should output all the sensible configuration values for the resources (like S3 bucket names, RDS endpoint URLs, etc.). Then, using Terraform itself or some other tool to create/update an environment, an additional step would collect all those outputs, transform them into k8s ConfigMap manifests, and put them into the GitOps repo.\n\nFor the secrets, we can go several ways. The most simplistic (though not flexible and not easy for secret rotation) way is to use some kind of encryption at rest like Mozilla's SOPS so that the secrets are being encrypted when they are put into the GitOps repo and decrypted when deployed into K8s. Another (and better ?) way - do not store secrets at rest at all but use either a third-party tool like Hashicorp Vault (with dynamic secrets generation) or cloud native features like [AWS IAM Roles for Service Accounts](https://aws.amazon.com/blogs/containers/diving-into-iam-roles-for-service-accounts/).\n\n## Bootstrap the demo\n\nThe accompanying repository, https://gitlab.com/iLychevAD/ci-cd-for-a-multi-component-app, contains Terraform files that enable you to install a copy of the demo structure into your own GitLab account to see it in action:\n\n`*.tf` files in the root directory and in the `tf_modules` directory describe the structure and configuration of the GitLab projects and groups. In the `repo_content` directory there is a content for the GitLab repositories in the projects. The repositories are filled with those files by the Terraform scripts.\n\nThe demo was tested with GitLab Community Edition `15.0.0-pre revision 4bda1cc84df`. The Terraform scripts do not create any real resources but just imitate them using `null_resource` and `local-exec`.\n\nThe bootstrapping process is conducted inside a container image (see the steps below) so it's platform-agnostic and in terms of tools all you need to spin up the demo is some containerization engine installed on your PC (i.e., Docker, Podman, etc).\n\n**Steps**:\n\n1. In the GitLab web UI manually create a root group to bootstrap the demo into (see `root_gitlab_group.tf` for a web-link why it's not possible to automate). Notice its ID - you need to provide it at the next step.\n\n2. Clone this repository.\n    Download an official Hashicorp's Terraform image and enter its interactive shell. All the further commands are supposed to be performed inside that shell:\n\n    ```shell\n    docker run --rm -it --name ci-cd-for-a-multi-component-app \\\n      -e TF_VAR_gitlab_token=\\\u003Cyour GitLab account access token\\> \\\n      -v \\\u003Cpath to a location where to store ssh key-pairs on your PC\\>:/deploy-keys \\\n      -e TF_VAR_deploy_key_readwrite=/deploy-keys/ci-cd-for-a-multi-component-app-deploy-key.pub \\\n      -e TF_VAR_deploy_key_readonly=/deploy-keys/ci-cd-for-a-multi-component-app-deploy-key.pub \\\n      -e TF_VAR_root_gitlab_group_id=\\\u003CGitLab group ID\\> \\\n      -v \\\u003Cpath to the directory where you cloned the project into\\>:/repo -w /repo \\\n      --entrypoint /bin/sh \\\n      public.ecr.aws/hashicorp/terraform:1.1.9\n    ```\n\n    Explanation:\n\n    `-e TF_VAR_gitlab_token=\\\u003Cyour GitLab account access token\\>` - Terraform's `gitlab` provider needs a GitLab access token with sufficient permissions to spin up the demo. Provide it as a Bash environment variable - `TF_VAR_gitlab_token` (see `provider.tf`). It is also used by the `upload_avatar` module.\n\n    `-v \\\u003Cpath to a location where to store ssh key-pairs on your PC\\>:/deploy-keys` - on the left-hand side here specify some directory on your local PC where you would like to store SSH keys needed for deploying the demo. Thus they are persisted even if you exit the container. See bullet point `4` for more details.\n\n    `-e TF_VAR_deploy_key_readwrite=/deploy-keys/ci-cd-for-a-multi-component-app-deploy-key` and\n\n    `-e TF_VAR_deploy_key_readonly=/deploy-keys/ci-cd-for-a-multi-component-app-deploy-key` - set the names for the aforementioned keys\n\n    `-v \\\u003Cpath to the directory where you cloned the project into\\>:/repo -w /repo` - we mount the project content from your local PC into the running container. Note that because of that the Terraform local state file will be stored inside that directory on your PC.\n\n3. Install tools - bash and curl:\n\n    ```shell\n    apk add bash curl\n\n    /bin/bash\n    ```\n\n4. Upon bootstrapping the demo, the repositories' content is pushed into (i.e. is restored) from the `repo_content` directory. (When the demo is destroyed the content of the repositories is automatically pulled (i.e. is saved) into the same directory - probably you dont need this but I implemented that for my convinience during creating the demo.) We need to create an SSH key pair and need it be the same throughout both phases. In this step we generate it:\n\n    ```shell\n    ssh-keygen -t rsa -N '' -f /deploy-keys/ci-cd-for-a-multi-component-app-deploy-key \u003C\u003C\u003C y\n    ```\n\n    ```shell\n    chmod 0400 /deploy-keys/ci-cd-for-a-multi-component-app-deploy-key\n    ```\n\n    A trick used in `tf_modules/gitlab_project_with_restore_backup/main.tf` requires that in the host section of the SSH public key the location of the private key is specified (in a form like `filename@~/.ssh/\u003Cfilename>`). Otherwise the `tf_modules/gitlab_project_with_restore_backup` won't work. Edit accordingly:\n\n    ```shell\n    sed -i -e 's|^\\(ssh-rsa .*\\) \\(.*\\)$|\\1 ci-cd-for-a-multi-component-app-deploy-key@/deploy-keys/ci-cd-for-a-multi-component-app-deploy-key|' /deploy-keys/ci-cd-for-a-multi-component-app-deploy-key.pub\n    ```\n\nNow you can proceed with bootstrapping the demo using Terraform:\n\nInitialize Terraform by `terraform init` so it installs all the providers.\n\nDeploy the demo with Terraform by `terraform apply`.\n\n**Notice**: During Terraform execution you may see an error:\n```text\nError: POST https://gitlab.com/api/v4/projects/multi-component-app-root-group/ci/library/deploy_keys: 400 {message: {deploy_key.fingerprint_sha256: [has already been taken]}}\n```\nI believe this is some glitch in the GitLab API. To fix just run `terraform apply` once again until it shows no errors.\n\nAfter that you should see the following structure in GitLab in the root group:\n\n![gitlab_projects_tree](https://about.gitlab.com/images/blogimages/migration-from-atlassian-bamboo-server-to-gitlab-ci/gitlab_projects_tree.png)\n\nAll the projects should be filled with files from the `repo_content` directory.\n\nDo not delete the directory with the cloned project and the files created inside it if later you would want to clean up the things. See the next section for instructions.\n\n## Cleaning up\n\nLaunch a container image the same way you did for bootstrapping the demo (see the previous section). It's supposed that you didnt delete any files in \\\u003Cpath to a location where to store ssh key-pairs on your PC\\> and \\\u003Cpath to the direcory where you cloned the project into\\>:\n\n```shell\ndocker run --rm -it --name ci-cd-for-a-multi-component-app \\\n  -e TF_VAR_gitlab_token=\\\u003Cyour GitLab account access token\\> \\\n  -v \\\u003Cpath to a location where to store ssh key-pairs on your PC\\>:/deploy-keys \\\n  -e TF_VAR_deploy_key_readwrite=/deploy-keys/ci-cd-for-a-multi-component-app-deploy-key.pub \\\n  -e TF_VAR_deploy_key_readonly=/deploy-keys/ci-cd-for-a-multi-component-app-deploy-key.pub \\\n  -e TF_VAR_root_gitlab_group_id=\\\u003CGitLab group ID\\> \\\n  -v \\\u003Cpath to the direcory where you cloned the project into\\>:/repo -w /repo \\\n  --entrypoint /bin/sh \\\n  public.ecr.aws/hashicorp/terraform:1.1.9\n\n```\n\nInstall curl:\n\n```shell apk add curl ```\n\nDo `terraform destroy`.\n\n**Notice**: You may see some errors regarding deleting the `oci-registry` project with OCI images. In that case just delete the images and remove the project manually or wait while GitLab does that itself later.\n\nNow if you want you can remove the cloned project directory and the \\\u003Cpath to a location where to store ssh key-pairs on your PC\\> directory.\n\nIf you would like to deploy the demo once again without removing the directory with the cloned repo dont forget to remove files created during the previous demo deployment, namely `terraform.tfstate` files in the root directory and `.git` directories everywhere in the `repo_content` directory.\n\nIn the [second part](/blog/how-to-migrate-atlassians-bamboo-servers-ci-cd-infrastructure-to-gitlab-ci-part-two/) of this tutorial, we'll look at a real-world example of how this can work.\n\n\n\n\n\n",[23,24,25],"CI/CD","DevOps","tutorial","yml",{},true,"/en-us/blog/migration-from-atlassian-bamboo-server-to-gitlab-ci",{"title":31,"description":16,"ogTitle":31,"ogDescription":16,"noIndex":12,"ogImage":19,"ogUrl":32,"ogSiteName":33,"ogType":34,"canonicalUrls":32},"Migrating

IIT Bombay students are coding the future with GitLab","At GitLab, we often talk about how software accelerates innovation. But sometimes, you have to step away from the Zoom calls and stand in a crowded university hall to remember why we do this.",[708],"Nick Veenhof","https://res.cloudinary.com/about-gitlab-com/image/upload/v1750099013/Blog/Hero%20Images/Blog/Hero%20Images/blog-image-template-1800x945%20%2814%29_6VTUA8mUhOZNDaRVNPeKwl_1750099012960.png","2026-01-08",[261,610,712],"open source","The GitLab team recently had the privilege of judging the **iHack Hackathon** at **IIT Bombay's E-Summit**. The energy was electric, the coffee was flowing, and the talent was undeniable. But what struck us most wasn't just the code — it was the sheer determination of students to solve real-world problems, often overcoming significant logistical and financial hurdles to simply be in the room.\n\n\nThrough our [GitLab for Education program](https://about.gitlab.com/solutions/education/), we aim to empower the next generation of developers with tools and opportunity. Here is a look at what the students built, and how they used GitLab to bridge the gap between idea and reality.\n\n## The challenge: Build faster, build securely\n\nThe premise for the GitLab track of the hackathon was simple: Don't just show us a product; show us how you built it. We wanted to see how students utilized GitLab's platform — from Issue Boards to CI/CD pipelines — to accelerate the development lifecycle.\n\nThe results were inspiring.\n\n## The winners\n\n### 1st place: Team Decode — Democratizing Scientific Research\n\n**Project:** FIRE (Fast Integrated Research Environment)\n\nTeam Decode took home the top prize with a solution that warms a developer's heart: a local-first, blazing-fast data processing tool built with [Rust](https://about.gitlab.com/blog/secure-rust-development-with-gitlab/) and Tauri. They identified a massive pain point for data science students: existing tools are fragmented, slow, and expensive.\n\nTheir solution, FIRE, allows researchers to visualize complex formats (like NetCDF) instantly. What impressed the judges most was their \"hacker\" ethos. They didn't just build a tool; they built it to be open and accessible.\n\n**How they used GitLab:** Since the team lived far apart, asynchronous communication was key. They utilized **GitLab Issue Boards** and **Milestones** to track progress and integrated their repo with Telegram to get real-time push notifications. As one team member noted, \"Coordinating all these technologies was really difficult, and what helped us was GitLab... the Issue Board really helped us track who was doing what.\"\n\n![Team Decode](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380253/epqazj1jc5c7zkgqun9h.jpg)\n\n### 2nd place: Team BichdeHueDost — Reuniting to Solve Payments\n\n**Project:** SemiPay (RFID Cashless Payment for Schools)\n\nThe team name, BichdeHueDost, translates to \"Friends who have been set apart.\" It's a fitting name for a group of friends who went to different colleges but reunited to build this project. They tackled a unique problem: handling cash in schools for young children. Their solution used RFID cards backed by a blockchain ledger to ensure secure, cashless transactions for students.\n\n**How they used GitLab:** They utilized [GitLab CI/CD](https://about.gitlab.com/topics/ci-cd/) to automate the build process for their Flutter application (APK), ensuring that every commit resulted in a testable artifact. This allowed them to iterate quickly despite the \"flaky\" nature of cross-platform mobile development.\n\n![Team BichdeHueDost](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380253/pkukrjgx2miukb6nrj5g.jpg)\n\n### 3rd place: Team ZenYukti — Agentic Repository Intelligence\n\n**Project:** RepoInsight AI (AI-powered, GitLab-native intelligence platform)\n\nTeam ZenYukti impressed us with a solution that tackles a universal developer pain point: understanding unfamiliar codebases. What stood out to the judges was the tool's practical approach to onboarding and code comprehension: RepoInsight-AI automatically generates documentation, visualizes repository structure, and even helps identify bugs, all while maintaining context about the entire codebase.\n\n**How they used GitLab:** The team built a comprehensive CI/CD pipeline that showcased GitLab's security and DevOps capabilities. They integrated [GitLab's Security Templates](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/gitlab/ci/templates/Security) (SAST, Dependency Scanning, and Secret Detection), and utilized [GitLab Container Registry](https://docs.gitlab.com/user/packages/container_registry/) to manage their Docker images for backend and frontend components. They created an AI auto-review bot that runs on merge requests, demonstrating an \"agentic workflow\" where AI assists in the development process itself.\n\n![Team ZenYukti](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380253/ymlzqoruv5al1secatba.jpg)\n\n## Beyond the code: A lesson in inclusion\n\nWhile the code was impressive, the most powerful moment of the event happened away from the keyboard.\n\nDuring the feedback session, we learned about the journey Team ZenYukti took to get to Mumbai. They traveled over 24 hours, covering nearly 1,800 kilometers. Because flights were too expensive and trains were booked, they traveled in the \"General Coach,\" a non-reserved, severely overcrowded carriage.\n\nAs one student described it:\n\n*\"You cannot even imagine something like this... there are no seats... people sit on the top of the train. This is what we have endured.\"*\n\nThis hit home. [Diversity, Inclusion, and Belonging](https://handbook.gitlab.com/handbook/company/culture/inclusion/) are core values at GitLab. We realized that for these students, the barrier to entry wasn't intellect or skill, it was access.\n\nIn that moment, we decided to break that barrier. We committed to reimbursing the travel expenses for the participants who struggled to get there. It's a small step, but it underlines a massive truth: **talent is distributed equally, but opportunity is not.**\n\n![hackathon class together](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380252/o5aqmboquz8ehusxvgom.jpg)\n\n### The future is bright (and automated)\n\nWe also saw incredible potential in teams like Prometheus, who attempted to build an autonomous patch remediation tool (DevGuardian), and Team Arrakis, who built a voice-first job portal for blue-collar workers using [GitLab Duo](https://about.gitlab.com/gitlab-duo/) to troubleshoot their pipelines.\n\nTo all the students who participated: You are the future. Through [GitLab for Education](https://about.gitlab.com/solutions/education/), we are committed to providing you with the top-tier tools (like GitLab Ultimate) you need to learn, collaborate, and change the world — whether you are coding from a dorm room, a lab, or a train carriage. **Keep shipping.**\n\n> :bulb: Learn more about the [GitLab for Education program](https://about.gitlab.com/solutions/education/).\n",{"slug":715,"featured":12,"template":13},"how-iit-bombay-students-code-future-with-gitlab",{"content":717,"config":726},{"title":718,"description":719,"authors":720,"heroImage":721,"date":722,"category":9,"tags":723,"body":725},"Artois University elevates research and curriculum with GitLab Ultimate for Education","Artois University's CRIL leveraged the GitLab for Education program to gain free access to Ultimate, transforming advanced research and computer science curricula.",[708],"https://res.cloudinary.com/about-gitlab-com/image/upload/v1750099203/Blog/Hero%20Images/Blog/Hero%20Images/blog-image-template-1800x945%20%2820%29_2bJGC5ZP3WheoqzlLT05C5_1750099203484.png","2025-12-10",[610,261,724],"product","Leading academic institutions face a critical challenge: how to provide thousands of students and researchers with industry-standard, **full-featured DevSecOps tools** without compromising institutional control. Many start with basic version control, but the modern curriculum demands integrated capabilities for planning, security, and advanced CI/CD.\n\nThe **GitLab for Education program** is designed to solve this by providing access to **GitLab Ultimate** for qualifying institutions, allowing them to scale their operations and elevate their academic offerings. \n\nThis article showcases a powerful success story from the **Centre de Recherche en Informatique de Lens (CRIL)**, a joint laboratory of **Artois University** and CNRS in France. After years of relying solely on GitLab Community Edition (CE), the university's move to GitLab Ultimate through the GitLab for Education program immediately unlocked advanced capabilities, transforming their teaching, research, and contribution workflows virtually overnight. This story demonstrates why GitLab Ultimate is essential for institutions seeking to deliver advanced computer science and research curricula.\n\n## GitLab Ultimate unlocked: Managing scale and driving academic value\n\n**Artois University's** self-managed GitLab instance is a large-scale operation, supporting nearly **3,000 users** across approximately **19,000 projects**, primarily serving computer science students and researchers. While GitLab Community Edition was robust, the upgrade to GitLab Ultimate provided the sophisticated tooling necessary for managing this scale and facilitating advanced university-level work.\n\n***\"We can see the difference,\" says Daniel Le Berre, head of research at CRIL and the instance maintainer. \"It's a completely different product. Each week reveals new features that directly enhance our productivity and teaching.\"***\n\nThe institution joined the GitLab for Education program specifically because it covers both **instructional and non-commercial research use cases** and offers full access to Ultimate's features, removing significant cost barriers.\n\n### Key GitLab Ultimate benefits for students and researchers\n\n* **Advanced project management at scale:** Master's students now benefit from **GitLab Ultimate's project planning features**. This enables them to structure, track, and manage complex, long-term research projects using professional methodologies like portfolio management and advanced issue tracking that seamlessly roll up across their thousands of projects.\n\n* **Enhanced visibility:** Features like improved dashboards and code previews directly in Markdown files dramatically streamline tracking and documentation review, reducing administrative friction for both instructors and students managing large project loads.\n\n## Comprehensive curriculum: From concepts to continuous delivery\n\nGitLab Ultimate is deeply integrated into the computer science curriculum, moving students beyond simple `git` commands to practical **DevSecOps implementation**.\n\n* **Git fundamentals:** Students begin by visualizing concepts using open-source tools to master Git concepts.\n\n* **Full CI/CD implementation:** Students use GitLab CI for rigorous **Test-Driven Development (TDD)** in their software projects. They learn to build, test, and perform quality assurance using unit and integration testing pipelines—core competency made seamless by the integrated platform.\n\n* **DevSecOps for research and documentation:** The university teaches students that DevSecOps principles are vital for all collaborative work. Inspired by earlier work in Delft, students manage and produce critical research documentation (PDFs from Markdown files) using GitLab, incorporating quality checks like linters and spell checks directly in the CI pipeline. This ensures high-quality, reproducible research output.\n\n* **Future-proofing security skills:** The GitLab Ultimate platform immediately positions the institution to incorporate advanced DevSecOps features like SAST and DAST scanning as their research and development code projects grow, ensuring students are prepared for industry security standards.\n\n## Accelerating open source contributions with GitLab Duo\n\nAccess to the full GitLab platform, including our AI capabilities, has empowered students to make impactful contributions to the wider open source community faster than ever before.\n\nTwo Master's students recently completed direct contributions to the GitLab product, adding the **ORCID identifier** into user profiles. Working on GitLab.com, they leveraged **GitLab Duo's AI chat and code suggestions** to navigate the codebase efficiently.\n\n***\"This would not have been possible without GitLab Duo,\" Daniel Le Berre notes. \"The AI features helped students, who might have lacked deep codebase knowledge, deliver meaningful contributions in just two weeks.\"***\n\nThis demonstrates how providing students with cutting-edge tools **accelerates their learning and impact**, allowing them to translate classroom knowledge into real-world contributions immediately.\n\n## Empowering open research and institutional control\n\nThe stability of the self-managed instance at Artois University is key to its success. This model guarantees **institutional control and stability** — a critical factor for long-term research preservation.\n\nThe institution's expertise in this area was recently highlighted in a major 2024 study led by CRIL, titled: \"[Higher Education and Research Forges in France - Definition, uses, limitations encountered and needs analysis](https://hal.science/hal-04208924v4)\" ([Project on GitLab](https://gitlab.in2p3.fr/coso-college-codes-sources-et-logiciels/forges-esr-en)). The research found that the vast majority of public forges in French Higher Education and Research relied on **GitLab**. This finding underscores the consensus among academic leaders that self-hosted solutions are essential for **data control and longevity**, especially when compared to relying on external, commercial forges.\n\n## Unlock GitLab Ultimate for your institution today\n\nThe success story of **Artois University's CRIL** proves the transformative power of the GitLab for Education program. By providing **free access to GitLab Ultimate**, we enable large-scale institutions to:\n\n1.  **Deliver a modern, integrated DevSecOps curriculum.**\n\n2.  **Support advanced, collaborative research projects with Ultimate planning features.**\n\n3.  **Empower students to make AI-assisted open source contributions.**\n\n4.  **Maintain institutional control and data longevity.**\n\nIf your academic institution is ready to equip its students and researchers with the complete DevSecOps platform and its most advanced features, we invite you to join the program.\n\nThe program provides **free access to GitLab Ultimate** for qualifying instructional and non-commercial research use cases.\n\n**Apply now [online](https://about.gitlab.com/solutions/education/join/).**\n",{"slug":727,"featured":28,"template":13},"artois-university-elevates-curriculum-with-gitlab-ultimate-for-education",{"content":729,"config":741},{"category":9,"tags":730,"body":732,"date":733,"updatedDate":734,"heroImage":735,"authors":736,"title":739,"description":740},[25,731,23],"git","\nEnterprise teams are increasingly migrating from Azure DevOps to GitLab to gain strategic advantages and accelerate secure software delivery. \n\n\n- GitLab comes with integrated controls, policies, and [compliance frameworks](https://docs.gitlab.com/user/compliance/compliance_frameworks/) that allow organizations to implement software delivery standards at scale. This is especially important for regulated industries.\n\n- [Security testing](https://docs.gitlab.com/user/application_security/) is embedded in the pipeline and results show in the developer workflow, including static application security testing (SAST), source code analysis (SCA), dynamic application security testing (DAST), infrastructure-as-code scanning (IaC), container scanning, and API scanning.\n\n- [AI capabilities](https://about.gitlab.com/gitlab-duo-agent-platform/) across the full software delivery lifecycle include advanced agent orchestration and customizable flows to support how your organizational teams work.\n\n\nGitLab's open-source, open-core approach, flexible deployment options such as single-tenant dedicated and self-managed, and truly unified platform eliminate integration complexity and security gaps. \n\n\nFor teams facing mounting pressure to accelerate delivery while strengthening security posture and maintaining regulatory compliance, GitLab represents not just a migration but a platform evolution.\n\n\nMigrating from Azure DevOps to GitLab can seem like a daunting task, but with the right approach and tools, it can be a smooth and efficient process. This guide will walk you through the steps needed to successfully migrate your projects, repositories, and pipelines from Azure DevOps to GitLab.\n\n\n## Overview\n\nGitLab provides both [Congregate](https://gitlab.com/gitlab-org/professional-services-automation/tools/migration/congregate/) (maintained by [GitLab Professional Services](https://about.gitlab.com/professional-services/) organization) and [a built-in Git repository import](https://docs.gitlab.com/user/project/import/repo_by_url/) for migrating projects from Azure DevOps (ADO). These options support repository-by-repository or bulk migration and preserve git commit history, branches, and tags. With Congregate and professional services tools, we support additional assets such as wikis, work items, CI/CD variables, container images, packages, pipelines, and more (see this [feature matrix](https://gitlab.com/gitlab-org/professional-services-automation/tools/migration/congregate/-/blob/master/customer/ado-migration-features-matrix.md)). Use this guide to plan and execute your migration and complete post-migration follow-up tasks.\n\n\nEnterprises migrating from ADO to GitLab commonly follow a multi-phase approach:\n\n\n- Migrate repositories from ADO to GitLab using Congregate or GitLab's built-in repository migration.\n\n- Migrate pipelines from Azure Pipelines to GitLab CI/CD.\n\n- Migrate remaining assets such as boards, work items, and artifacts to GitLab Issues, Epics, and the Package and Container Registries.\n\n\nHigh-level migration phases:\n\n\n```mermaid\ngraph LR\n    subgraph Prerequisites\n        direction TB\n        A[\"Set up identity provider (IdP) and\u003Cbr/>provision users\"]\n        A --> B[\"Set up runners and\u003Cbr/>third-party integrations\"]\n        B --> I[\"Users enablement and\u003Cbr/>change management\"]\n    end\n    \n    subgraph MigrationPhase[\"Migration phase\"]\n        direction TB\n        C[\"Migrate source code\"]\n        C --> D[\"Preserve contributions and\u003Cbr/> format history\"]\n        D --> E[\"Migrate work items and\u003Cbr/>map to \u003Ca href=\"https://docs.gitlab.com/topics/plan_and_track/\">GitLab Plan \u003Cbr/>and track work\"]\n    end\n    \n    subgraph PostMigration[\"Post-migration steps\"]\n        direction TB\n        F[\"Create or translate \u003Cbr/>ADO pipelines to GitLab CI\"]\n        F --> G[\"Migrate other assets\u003Cbr/>packages and container images\"]\n        G --> H[\"Introduce \u003Ca href=\"https://docs.gitlab.com/user/application_security/secure_your_application/\">security\u003C/a> and\u003Cbr/>SDLC improvements\"]\n    end\n    \n    Prerequisites --> MigrationPhase\n    MigrationPhase --> PostMigration\n\n    style A fill:#FC6D26\n    style B fill:#FC6D26\n    style I fill:#FC6D26\n    style C fill:#8C929D\n    style D fill:#8C929D\n    style E fill:#8C929D\n    style F fill:#FFA500\n    style G fill:#FFA500\n    style H fill:#FFA500\n```\n\n\n## Planning your migration\n\n\n**To plan your migration, ask these questions:**\n\n\n- How soon do we need to complete the migration?\n\n- Do we understand what will be migrated?\n\n- Who will run the migration?\n\n- What organizational structure do we want in GitLab?\n\n- Are there any constraints, limitations, or pitfalls that need to be taken into account?\n\n\nDetermine your timeline, as it will largely dictate your migration approach. Identify champions or groups familiar with both ADO and GitLab platforms (such as early adopters) to help drive adoption and provide guidance.\n\n\n**Inventory what you need to migrate:**\n\n\n- The number of repositories, pull requests, and contributors\n\n- The number and complexity of work items and pipelines\n\n- Repository sizes and dependency relationships\n\n- Critical integrations and runner requirements (agent pools with specific capabilities)\n\n\nUse GitLab Professional Services's [Evaluate](https://gitlab.com/gitlab-org/professional-services-automation/tools/utilities/evaluate#beta-azure-devops) tool to produce a complete inventory of your entire Azure DevOps organization, including repositories, PR counts, contributor lists, number of pipelines, work items, CI/CD variables and more. If you're working with the GitLab Professional Services team, share this report with your engagement manager or technical architect to help plan the migration.\n\n\nMigration timing is primarily driven by pull request count, repository size, and amount of contributions (e.g. comments in PR, work items, etc). For example, 1,000 small repositories with few PRs and limited contributors can migrate much faster than a smaller set of repositories containing tens of thousands of PRs and thousands of contributors. Use your inventory data to estimate effort and plan test runs before proceeding with production migrations.\n\n\nCompare inventory against your desired timeline and decide whether to migrate all repositories at once or in batches. If teams cannot migrate simultaneously, batch and stagger migrations to align with team schedules. For example, in Professional Services engagements, we organize migrations into waves of 200-300 projects to manage complexity and respect API rate limits, both in [GitLab](https://docs.gitlab.com/security/rate_limits/) and [ADO](https://learn.microsoft.com/en-us/azure/devops/integrate/concepts/rate-limits?view=azure-devops).\n\n\nGitLab's built-in [repository importer](https://docs.gitlab.com/user/project/import/repo_by_url/) migrates Git repositories (commits, branches, and tags) one-by-one. Congregate is designed to preserve pull requests (known in GitLab as merge requests), comments, and related metadata where possible; the simple built-in repository import focuses only on the Git data (history, branches, and tags).\n\n\n**Items that typically require separate migration or manual recreation:**\n\n\n- Azure Pipelines - create equivalent GitLab CI/CD pipelines (consult with [CI/CD YAML](https://docs.gitlab.com/ci/yaml/) and/or with [CI/CD components](https://docs.gitlab.com/ci/components/)). Alternatively, consider using AI-based pipeline conversion available in Congregate.\n\n- Work items and boards - map to GitLab Issues, Epics, and Issue Boards.\n\n- Artifacts, container images (ACR) - migrate to GitLab Package Registry or Container Registry.\n\n- Service hooks and external integrations - recreate in GitLab.\n\n- [Permissions models](https://docs.gitlab.com/user/permissions/) differ between ADO and GitLab; review and plan permissions mapping rather than assuming exact preservation.\n\n\nReview what each tool (Congregate vs. built-in import) will migrate and choose the one that fits your needs. Make a list of any data or integrations that must be migrated or recreated manually.\n\n\n**Who will run the migration?**\n\n\nMigrations are typically run by a GitLab group owner or instance administrator, or by a designated migrator who has been granted the necessary permissions on the destination group/project. Congregate and the GitLab import APIs require valid authentication tokens for both Azure DevOps and GitLab.\n\n\n- Decide whether a group owner/admin will perform the migrations or whether you will grant a specific team/person delegated access.\n\n- Ensure the migrator has correctly configured personal access tokens (Azure DevOps and GitLab) with the scopes required by your chosen migration tool (for example, api/read_repository scopes and any tool-specific requirements). \n\n- Test tokens and permissions with a small pilot migration.\n\n**Note:** Congregate leverages file-based import functionality for ADO migrations and requires instance administrator permissions to run ([see our documentation](https://docs.gitlab.com/user/project/settings/import_export/#migrate-projects-by-uploading-an-export-file)). If you are migrating to GitLab.com, consider engaging Professional Services. For more information, see the [Professional Services Full Catalog](https://about.gitlab.com/professional-services/catalog/). Non-admin account cannot preserve contribution attribution!\n\n\n**What organizational structure do we want in GitLab?**\n\nWhile it's possible to map ADO structure directly to GitLab structure, it's recommended to rationalize and simplify the structure during migration. Consider how teams will work in GitLab and design the structure to facilitate collaboration and access management. Here is a way to think about mapping ADO structure to GitLab structure:\n\n\n```mermaid\ngraph TD\n    subgraph GitLab\n        direction TB\n        A[\"Top-level Group\"]\n        B[\"Subgroup (optional)\"]\n        C[\"Projects\"]\n        A --> B\n        A --> C\n        B --> C\n    end\n\n    subgraph AzureDevOps[\"Azure DevOps\"]\n        direction TB\n        F[\"Organizations\"]\n        G[\"Projects\"]\n        H[\"Repositories\"]\n        F --> G\n        G --> H\n    end\n\n    style A fill:#FC6D26\n    style B fill:#FC6D26\n    style C fill:#FC6D26\n    style F fill:#8C929D\n    style G fill:#8C929D\n    style H fill:#8C929D\n```\n\nRecommended approach:\n\n\n- Map each ADO organization to a GitLab group (or a small set of groups), not to many small groups. Avoid creating a GitLab group for every ADO team project. Use migration as an opportunity to rationalize your GitLab structure.\n\n- Use subgroups and project-level permissions to group related repositories.\n\n- Manage access to sets of projects by using GitLab groups and group membership (groups and subgroups) rather than one group per team project.\n\n- Review GitLab [permissions](https://docs.gitlab.com/ee/user/permissions.html) and consider [SAML Group Links](https://docs.gitlab.com/user/group/saml_sso/group_sync/) to implement an enterprise RBAC model for your GitLab instance (or a GitLab.com namespace).\n\n\n**ADO Boards and work items: State of migration**\n\n\nIt's important to understand how work items migrate from ADO into GitLab Plan (issues, epics, and boards).\n\n\n- ADO Boards and work items map to GitLab Issues, Epics, and Issue Boards. Plan how your workflows and board configurations will translate.\n\n- ADO Epics and Features become GitLab Epics.\n\n- Other work item types (e.g., user stories, tasks, bugs) become project-scoped issues.\n\n- Most standard fields are preserved; selected custom fields can be migrated when supported.\n\n- Parent-child relationships are retained so Epics reference all related issues.\n\n- Links to pull requests are converted to merge request links to maintain development traceability.\n\n\nExample: Migration of an individual work item to a GitLab Issue, including field accuracy and relationships:\n\n\n![Example: Migration of an individual work item to a GitLab Issue](https://res.cloudinary.com/about-gitlab-com/image/upload/v1764769188/ztesjnxxfbwmfmtckyga.png)\n\n\nBatching guidance:\n\n\n- If you need to run migrations in batches, use your new group/subgroup structure to define batches (for example, by ADO organization or by product area).\n\n- Use inventory reports to drive batch selection and test each batch with a pilot migration before scaling.\n\n\n**Pipelines migration**\n\n\nCongregate [recently introduced](https://gitlab.com/gitlab-org/professional-services-automation/tools/migration/congregate/-/merge_requests/1298) AI-powered conversion for multi-stage YAML pipelines from Azure DevOps to GitLab CI/CD. This automated conversion works best for simple, single-file pipelines and is designed to provide a working starting point rather than a production-ready `.gitlab-ci.yml` file. The tool generates a functionally equivalent GitLab pipeline that you can then refine and optimize for your specific needs.\n\n\n- Converts Azure Pipelines YAML to `.gitlab-ci.yml` format automatically.\n\n- Best suited for straightforward, single-file pipeline configurations.\n\n- Provides a boilerplate to accelerate migration, not a final production artifact.\n\n- Requires review and adjustment for complex scenarios, custom tasks, or enterprise requirements.\n\n- Does not support Azure DevOps classic release pipelines — [convert these to multi-stage YAML](https://learn.microsoft.com/en-us/azure/devops/pipelines/release/from-classic-pipelines?view=azure-devops) first.\n\n\nRepository owners should review the [GitLab CI/CD documentation](https://docs.gitlab.com/ci/) to further optimize and enhance their pipelines after the initial conversion.\n\n\nExample of converted pipelines:\n\n\n```yml \n\n# azure-pipelines.yml\n\ntrigger:\n  - main\n\nvariables:\n  imageName: myapp\n\nstages:\n  - stage: Build\n    jobs:\n      - job: Build\n        pool:\n          vmImage: 'ubuntu-latest'\n        steps:\n          - checkout: self\n\n          - task: Docker@2\n            displayName: Build Docker image\n            inputs:\n              command: build\n              repository: $(imageName)\n              Dockerfile: '**/Dockerfile'\n              tags: |\n                $(Build.BuildId)\n\n  - stage: Test\n    jobs:\n      - job: Test\n        pool:\n          vmImage: 'ubuntu-latest'\n        steps:\n          - checkout: self\n\n          # Example: run tests inside the container\n          - script: |\n              docker run --rm $(imageName):$(Build.BuildId) npm test\n            displayName: Run tests\n\n  - stage: Push\n    jobs:\n      - job: Push\n        pool:\n          vmImage: 'ubuntu-latest'\n        steps:\n          - checkout: self\n\n          - task: Docker@2\n            displayName: Login to ACR\n            inputs:\n              command: login\n              containerRegistry: '\u003Cyour-acr-service-connection>'\n\n          - task: Docker@2\n            displayName: Push image to ACR\n            inputs:\n              command: push\n              repository: $(imageName)\n              tags: |\n                $(Build.BuildId)\n\n```\n\n```yaml\n\n# .gitlab-ci.yml\n\nvariables:\n  imageName: myapp\n\nstages:\n  - build\n  - test\n  - push\n\nbuild:\n  stage: build\n  image: docker:latest\n  services:\n    - docker:dind\n  script:\n    - docker build -t $imageName:$CI_PIPELINE_ID -f $(find . -name Dockerfile) .\n  only:\n    - main\n\ntest:\n  stage: test\n  image: docker:latest\n  services:\n    - docker:dind\n  script:\n    - docker run --rm $imageName:$CI_PIPELINE_ID npm test\n  only:\n    - main\n\npush:\n  stage: push\n  image: docker:latest\n  services:\n    - docker:dind\n  before_script:\n    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY\n  script:\n    - docker tag $imageName:$CI_PIPELINE_ID $CI_REGISTRY/$CI_PROJECT_PATH/$imageName:$CI_PIPELINE_ID\n    - docker push $CI_REGISTRY/$CI_PROJECT_PATH/$imageName:$CI_PIPELINE_ID\n  only:\n    - main\n\n```\n\n**Final checklist:**\n\n\n- Decide timeline and batch strategy.\n\n- Produce a full inventory of repositories, PRs, and contributors.\n\n- Choose Congregate or the built-in import based on scope (PRs and metadata vs. Git data only).\n\n- Decide who will run migrations and ensure tokens/permissions are configured.\n\n- Identify assets that must be migrated separately (pipelines, work items, artifacts, and hooks) and plan those efforts.\n\n- Run pilot migrations, validate results, then scale according to your plan.\n\n\n## Running your migrations\n\n\nAfter planning, execute migrations in stages, starting with trial runs. Trial migrations help surface org-specific issues early and let you measure duration, validate outcomes, and fine-tune your approach before production.\n\n\nWhat trial migrations validate:\n\n\n- Whether a given repository and related assets migrate successfully (history, branches, tags; plus MRs/comments if using Congregate)\n\n- Whether the destination is usable immediately (permissions, runners, CI/CD variables, integrations)\n\n- How long each batch takes, to set schedules and stakeholder expectations\n\n\nDowntime guidance:\n\n\n- GitLab's built-in Git import and Congregate do not inherently require downtime.\n\n- For production waves, freeze changes in ADO (branch protections or read-only) to avoid missed commits, PR updates, or work items created mid-migration.\n\n- Trial runs do not require freezes and can be run anytime.\n\n\nBatching guidance:\n\n\n- Run trial batches back-to-back to shorten elapsed time; let teams validate results asynchronously.\n\n- Use your planned group/subgroup structure to define batches and respect API rate limits.\n\n\nRecommended steps:\n\n\n1. Create a test destination in GitLab for trials:\n\n\n  - GitLab.com: create a dedicated group/namespace (for example, my-org-sandbox)\n\n  - Self-managed: create a top-level group or a separate test instance if needed\n\n\n2. Prepare authentication:\n\n\n  - Azure DevOps PAT with required scopes.\n\n  - GitLab Personal Access Token with api and read_repository (plus admin access for file-based imports used by Congregate).\n\n\n3. Run trial migrations:\n\n\n  - Repos only: use GitLab's built-in import (Repo by URL)\n\n  - Repos + PRs/MRs and additional assets: use Congregate\n\n\n4. Post-trial follow-up:\n\n\n  - Verify repo history, branches, tags; merge requests (if migrated), issues/epics (if migrated), labels, and relationships.\n\n  - Check permissions/roles, protected branches, required approvals, runners/tags, variables/secrets, integrations/webhooks.\n\n  - Validate pipelines (`.gitlab-ci.yml`) or converted pipelines where applicable.\n\n\n5. Ask users to validate functionality and data fidelity.\n\n6. Resolve issues uncovered during trials and update your runbooks.\n\n7. Network and security:\n\n\n  - If your destination uses IP allow lists, add the IPs of your migration host and any required runners/integrations so imports can succeed.\n\n\n8. Run production migrations in waves:\n\n\n  - Enforce change freezes in ADO during each wave.\n\n  - Monitor progress and logs; retry or adjust batch sizes if you hit rate limits.\n\n\n9. Optional: remove the sandbox group or archive it after you finish.\n\n\n\u003Cfigure class=\"video_container\">\n  \u003Ciframe src=\"https://www.youtube.com/embed/ibIXGfrVbi4?si=ZxOVnXjCF-h4Ne0N\" frameborder=\"0\" allowfullscreen=\"true\">\u003C/iframe>\n\u003C/figure>\n\n\n## Terminology reference for GitLab and Azure DevOps\n\n| GitLab                                                           | Azure DevOps                                 | Similarities & Key Differences                                                                                                                                          |\n| ---------------------------------------------------------------- | -------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| Group                                                            | Organization                                 | Top-level namespace, membership, policies.
