Ok so I could do a switchover to B and C and A become standbys, then remove A from the configuration before shutting it down and closing the data center? No hard failover. Thanks

Remove the old server from the redo routes before getting rid of it.

Currently we have a primary database (DB_A) and 2 standbys (DB_B & DB_C). We are planning on hard failing over to one of the standby databases to retire the current primary. To protect the future standby when it becomes primary, we would like to be able to have a standby right away if possible. When we fail over to DB_B, is there a way to make DB_C immediately be the standby for DB_B?

Instead of doing a failover, you would need to do a switchover. You should set up your redoroutes in advance in dgmgrl. You should also use this to test the configuration using the
Show configuration when primary is DB_B.
