Moving ASM database files to new diskgroup on a physical standby

 Hi All;

I want to move some datafiles to different diskgroups on a Data Guard standby. Just wanted some feedback on whether these steps would work:

- Cancel recovery on the standby to stop log applies.

- Use RMAN to copy the files to a new diskgroup

- Use RMAN set the newname, and switch the datafile

- Drop the old ASM datafile

- Restart recovery on the standby

I'm assuming the datafiles do not need to be offlined, and recovered since the database is in a mount state.

Thanks,

Charlie
