 If issues arise during migration, run MOLT Fetch in `failback` mode after stopping replication and before writing to CockroachDB. This ensures that data remains consistent on the source in case you need to roll back the migration.

 #### `data-load`
 
 `data-load` (default) instructs MOLT Fetch to load the source data into CockroachDB. It does not replicate any subsequent changes on the source.
