Actually, you can also create a new replicated volume, copy over all the
data, change the name of the rootvolume in /vice/db/ROOTVOLUME and
reinitialize the clients (so that they forget about the old rootvolume).

There is another alternative, which is a bit more 'experimental'.

As Ivan says, best best is to save all your existing data. In case
things go wrong you can then restore it.

I'll detail the experimental way in another message when I have a bit of
time. But it is worth a wait, because it might just be what you're
looking for.
