Defined in:

lib/gitlab/background_migration/legacy_uploads_migrator.rb

Overview

This migration takes all legacy uploads (that were uploaded using AttachmentUploader) and migrate them to the new (FileUploader) location (=under projects).

We have dependencies (uploaders) in this migration because extracting code would add a lot of complexity and possible errors could appear as the logic in the uploaders is not trivial.

This migration will be removed in 13.0 in order to get rid of a migration that depends on the application code.
