Check Details

Check requirements: oplogs can be obtained from the source database during full + incremental migration.
Check description: incremental migration requires oplogs for replay. If the oplog.rs or oplog.$main table does not exist in the source local database, oplogs cannot be obtained.

Fix

Start the source database as a replica set or in primary/secondary mode to ensure that oplogs can be generated for operations and recorded in the source local database.
