Migrate projects to a GitLab instance

See these documents to migrate to GitLab:

You can also import any Git repository through HTTP from the New Project page. Note that if the repository is too large, the import can timeout.

You can also connect your external repository to get CI/CD benefits. (PREMIUM)

LFS authentication

When importing a project that contains LFS objects, if the project has an .lfsconfig file with a URL host (lfs.url) different from the repository URL host, LFS files are not downloaded.

Migrate from self-managed GitLab to GitLab.com

If you only need to migrate Git repositories, you can import each project by URL. However, you can't import issues and merge requests this way. To retain all metadata like issues and merge requests, use the import/export feature to export projects from self-managed GitLab and import those projects into GitLab.com. All GitLab user associations (such as comment author) are changed to the user importing the project. For more information, see the import notes.

NOTE: When migrating to GitLab.com, you must create users manually unless SCIM will be used. Creating users with the API is limited to self-managed instances as it requires administrator access.

To migrate all data from self-managed to GitLab.com, you can leverage the API. Migrate the assets in this order:

Keep in mind the limitations of the import/export feature.

You must still migrate your Container Registry over a series of Docker pulls and pushes. Re-run any CI pipelines to retrieve any build artifacts.

Migrate from GitLab.com to self-managed GitLab

The process is essentially the same as migrating from self-managed GitLab to GitLab.com. The main difference is that an administrator can create users on the self-managed GitLab instance through the UI or the users API.

Migrate between two self-managed GitLab instances

To migrate from an existing self-managed GitLab instance to a new self-managed GitLab instance, it's best to back up the existing instance and restore it on the new instance. For example, this is useful when migrating a self-managed instance from an old server to a new server.

To instead merge two self-managed GitLab instances together, use the instructions in Migrate from self-managed GitLab to GitLab.com. This method is useful when both self-managed instances have existing data that must be preserved.

Also note that administrators can use the Users API to migrate users.

Project aliases (PREMIUM SELF)

Introduced in GitLab Premium 12.1.

GitLab repositories are usually accessed with a namespace and a project name. When migrating frequently accessed repositories to GitLab, however, you can use project aliases to access those repositories with the original name. Accessing repositories through a project alias reduces the risk associated with migrating such repositories.

This feature is only available on Git over SSH. Also, only GitLab administrators can create project aliases, and they can only do so through the API. For more information, see the Project Aliases API documentation.

After an administrator creates an alias for a project, you can use the alias to clone the repository. For example, if an administrator creates the alias gitlab for the project https://gitlab.com/gitlab-org/gitlab, you can clone the project with git clone git@gitlab.com:gitlab.git instead of git clone git@gitlab.com:gitlab-org/gitlab.git.
