Can I Migrate Data from a Multi-DB Source Redis Instance to a Cluster DCS Redis Instance?

A total of 256 DBs (DB 0 to DB 255) can be configured for a single-node or master/standby DCS instance.

• If the target is a cluster instance (a cluster instance has only one DB):

  Solutions:

  1. Combine different DBs in the source Redis instance into one DB.
  2. Apply for multiple DCS instances.

  After the migration, the instance connection address and DB IDs change. In this case, modify the configurations for your services.
