Checking Whether the Migration Is from an Earlier Database Version to the Same or a Later Version
For homogeneous migration, DRS checks whether data is migrated from an earlier version to a later version or the same version. The database of a later version has new features. If the destination database does not have such features, data migration may fail.
Failure Cause
Data cannot be migrated or synchronized from a newer version database to an older version database.
Handling Suggestion
Select a source or destination database version that meets requirements, or ensure that the source database does not use new features provided by a later version. Otherwise, the migration may fail.
