Dan, by far the fastest way is to add the new disks onto the disk group,
rebalance, then remove the old disks and rebalance. No downtime.

A colleague is trying to move a database from one ASM diskgroup on the

to move the database to it.
We are trying to determine the best way and fastest (tight deadline). Not a
lot of time for testing. The database is not production and we have an
export, but would rather not go through the process of totally recreating
it.
Does anyone have experience moving a db from one ASM diskgroup to another
diskgroup in the same instance?
Any experience with the following 10g command to accomplish this? (From Tim
Hall's site)
# Copy the database into the ASM disk group.
RMAN> BACKUP AS COPY DATABASE FORMAT '+disk_group';
# Switch all datafile to the new ASM location.
RMAN> SWITCH DATABASE TO COPY;
Any/All input greatly appreciated!

Daniel
