Is All Data in a DCS Redis Instance Migrated During Online Migration?
Migration among multi-DB single-node, read/write splitting, or master/standby instances involves the full set of data. After the migration, a given key will remain in the same DB as it was before the migration.
By contrast, a cluster instance only has one DB, which is DB0 by default. During the migration, data in all slots of DB0 is migrated.
