Restoring Data of Enhanced Edition

Scenarios

DDS 4.4 and DDS 4.4 Enhanced Edition (DDS 4.4 pro for short) are incompatible due to different underlying data storage structures. You can upgrade DDS 4.4 to DDS 4.4 pro in either of the following ways:

• Use DRS to migrate data from DDS 4.4 to DDS 4.4 pro. For details, see From On-Premises MongoDB to DDS.
• Contact customer service to upgrade DDS 4.4 to DDS 4.4 pro by rebuilding data on the original DB instance.

Precautions

• After data in a DDS DB instance is migrated to an enhanced binary system, backups before the migration cannot be restored to the original DB instance or a new DB instance.
• After data in a DDS DB instance is migrated to an enhanced binary system, backups cannot be restored to the time point before the migration.
• DDS enhanced binary data backups cannot be restored to on-premises databases.
