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.
Only one DB is configured for a cluster DCS instance.
Solutions:
- Combine different DBs in the source Redis instance into one DB.
- 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.
