What Shoud I Do If the Data Volume Is Inconsistent Before and After Data Migration?

Symptom

After CDM is used to migrate data, the number of data records in the destination database is dozens or thousands greater than that in the source database.

Fault Analysis

In the destination job configuration, Clear Data Before Import is set to No. As a result, multiple operations may be performed and duplicate data exists.

Solution

Set Clear Data Before Import to Yes. Rerun the migration job and check that the number of records is the same before and after the migration.
