  title: GitLab Start a Migration and Poll to Completion
  summary: Kick off a direct-transfer migration, then poll the import until it finishes.
  description: >-
    A GitLab-to-GitLab migration flow. The workflow starts a bulk import of a
    group or project from a source instance, then repeatedly reads the import
    status, looping while it is still in progress and ending once it reaches a
    terminal status. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.

    is created or started and ending when finished, failed, or timed out.
