Assuming your new location does not already have the ROs on it:

1 vos listvol to get the list of volumes to move; if the old location
is not empty, then, in this order:

2 For RO volumes: vos addsite to the new location, vos release, vos
remove old ROs
3 For RW volumes: vos move
4 For .backup volumes: vos backup (or backupsys, depending on how you
made them in the first place) once the RW volumes are moved
5 Goto 1

All this can be done while users are accessing their data, but if you
do this at a relatively quiet time you can avoid some potential
problems (eg, when this is done, snapshots are taken -- if the
volserver can't get a 'good' snapshot, the vos move will fail; clients
may see messages about a volume being busy; etc).
