Can RDS Primary/Standby DB Instances Be Changed to Single-Node DB Instances?
No. But you can change single-node instances to primary/standby instances. For details, see Changing a DB Instance Type from Single-Node to Primary/Standby. You can use Data Replication Service (DRS) or the export and import tool of the client to migrate data from primary/standby DB instances to single DB instances.
