Renaming or moving the controlfiles in oracle

1) sqlplus in to the database and get the location of the current control files...
     SQL> show parameter control_files;
2) make the desired directory structure where you want to move the controlfiles.
3) then in sqlplus, set the new location for the control files. AND Create a Pfile from existing SPFILE before making any CHANGES.
   SQL> ALTER SYSTEM SET control_files='+Apt/CONTROLFILE/control01.ctl','+TEMP/CONTROLFILE/control02.ctl' SCOPE=SPFILE;

4) shutdown the database;
5) start the database in nomount;
6) In another window, start rman ... rman target /
7) restore the control files to the above mentioned controlfiles from step 3 with a  current control file from old location from step 1.
  rman target /
restore controlfile to '+Apt/CONTROLFILE/control01.ctl'' from 'Apt/TESTDB/controlabc123';
restore controlfile to '+TEMP/CONTROLFILE/control02.ctl' fromn 'TEMP/TESTDB/controlabc123';

8) open the database in Mount.
