[5-4-stable to 6-0-stable]: rake migrate_global_projects fails when target directory not empty
Created by: Philzen
When the target directory {OWNER_NAMESPACE}/{PROJECT_DIR} already contains a repository the rake task will just respond with Cannot move project. \nF. No error information is displayed or found in the log.
Solution: rename or remove the target-empty directory to make way. Rake task will complete successfully after that.
