Move data may work, but migrate would work better.  Is this a File Class
pool, or a disk storage pool?  Set DISKPOOL1 as the "next storage pool"
for DISKPOOL2, and then kick off a migration.  You can throttle it by
setting the lowmig percentage to something that wouldn't take too long,
and then do it little bit at a time.  Or just set lowmig=0 and let it
run.

Examples:
Move data diskpool2vol recons=y stgpool=diskpool1 maxproc=1
Or
Update stg diskpool2 next=diskpool1 migprocess=2 (or however many you
want to run)
Migrate stg diskpool2 lowmig=0 (or the number of percentage you want to
migrate down to).

I'm sure others will have alternate ways, but these should work.
