if you also don't immediately need the old server, use vos move with
the -nodelete option; it will leave the old copies on the old server
behind (but not in the vldb)

i further assume you want to create new replicas rather than migrating
existing replicas (readonly volumes), if you want to move the old
ones, you can use vos dump and vos restore, and vos restore also
includes a -nodelete option.

you don't need to reconfigure clients fileserver-wise; if you're
moving database server functionality, you do need to deal with that on
the clients
