Clowning a database from Production backups using user managed backups - oracle 11g

Hi Gurus,

My Clown situation is as follows:

I have oracle 11.2 EE Database,  The OS is OEL 6 version.

Backups are taken everyday by using user managed backups.  Such as using statements like ALTER DATABASE BEGIN BACKUP;

Copying Data files from source location to target location;  ALTER DATABASE END BACKUP;

What I need is any documentation as how to clown my Production DB using backups taken as above (from instance_name: PDB)  and clown into another instance on another machine with different DB_UNIQUE_NAME like CDB(Clown DB).

Any help is much appreciated.
