I will put that a little more strongly: as soon as you update the master
copy, _all_ the guests have entirely the wrong idea of where files are
and what's in them: it's perfectly possible for space a client believes
is used by one file to be replaced with data from another.

I'd be planning on shutting down all the ro clients while the updates
are done.

I _think_ I'd have two masters, one to practice on and get right before
going live, and at least one test guest in which to test it's right. Do
you have a separate QA function to vet this?
