One-time migrations do not track activity in your data during a migration. If you create a one-time migration, your LiveData Migrator instance will not scan your source storage for updates to the data as the migration progresses.
A one-time migration does not write a marker file to the source storage. Once the scan of the source completes (to determine which files and directories are to be migrated), the migration will enter a
COMPLETED data migration state and won't perform any further scans.
