Move Database to another Home / Rman config

Hello,

I'm  about to move one and possible more of my 11.2.0.2 databases to another 11.2.0.2 home on the same server.
This is to separate production and non production databases from using the same Oracle Home.

All the databases use a Recovery catalog for their RMAN backups.

To move the databases to a new home do I need to deregister, before the move  and then re register the database with the recovery catalog after the move. ?

I notice that part of the rman config for databases is the "SNAPSHOT CONTROLFILE NAME TO 'ORACLE_HOME/dbs/snapcf_SID.f'

Thanks for any guidence.
