In my particular case, IPv6 offers no advantage when it comes to renumbering. It is just exactly as difficult to renumber with v6 as it is with v4. I do understand that in a lot of cases where end nodes are autoconfiguring based on RA it makes it easy but in many places that really isn't an option.
