Group repository storage moves API (PREMIUM SELF)

Introduced in GitLab 13.9.

Group repositories can be moved between storages. This API can help you when migrating to Gitaly Cluster, for example, or to migrate a group wiki.

As group repository storage moves are processed, they transition through different states. Values of state are:

initial: The record has been created, but the background job has not yet been scheduled.
scheduled: The background job has been scheduled.
started: The group repositories are being copied to the destination storage.
replicated: The group has been moved.
failed: The group repositories failed to copy, or the checksums did not match.
finished: The group has been moved, and the repositories on the source storage have been deleted.
cleanup failed: The group has been moved, but the repositories on the source storage could not be deleted.

To ensure data integrity, groups are put in a temporary read-only state for the duration of the move. During this time, users receive this message if they try to push new commits:

The repository is temporarily read-only. Please try again later.

This API requires you to authenticate yourself as an administrator.

APIs are also available to move other types of repositories:

GET /group_repository_storage_moves

By default, GET requests return 20 results at a time, because the API results are paginated.
