Is All Data in a DCS Redis Instance Migrated During Online Migration?

Migration between single-node and master/standby instances involves the full set of data. All DBs will be migrated, and you cannot migrate specified DBs. 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. During the migration, data in all slots of DB0 is migrated.
