We recently did this same thing.  Its obviously easiest if you can get
everything staged off first...but if not you do need to make sure the
path to the image doesn't change.  Links work well for this if you
need to change the mountpoint though.  I can confirm that NB doesn't
need to be shutdown also...as long as you're not writing to them
you're fine.
