Hi,
Let me make it clear, my question was how to move the control file from one ASM diskgroup into another ASM diskgroup using RMAN.

Try this:
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP NOMOUNT;
SQL> alter system set control_files='<ASM location1>,<ASM location2>' scope=spfile sid='*';
Then, use RMAN to actually create the new control files in ASM.
RMAN> restore controlfile from '<your current location>';

Regards
Michel

Thanks Michel. Just want to make sure I understand it right

Step 1.

SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP NOMOUNT;
SQL> alter system set control_files='<ASM NEW location1>,<ASM NEW location2>';
--We don't user spfile

$ rman nocatalog
RMAN>connect target /
RMAN> restore controlfile from '<ASM OLD location1>';


Step 2.

sql> alter database mount;
sql> alter database open;


Step 3. Change the init.ora parameter file, remove the old control file location and add new control file location

If you don't use spfile, replace the "alter system" to a modification of your init.ora.

But you should think about using a spfile, you lose many things with init.ora above all in RAC system.
