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.
