It seems like the work required for a network overhaul is sufficient that requiring the admin to pay attention and do a little work offline wouldn't be that big a deal. As long as there is a tool to do the migration that can handle overlaps, that seems good enough. Such a tool would be non-trivial, but is probably a good idea anyway. My view is that the sort of things that happen day to day should just work, and we should try to provide tools, or at least the outline of how such a tool would work for extraordinary situations like network renumbering. The real problem here is that there's no real chance of a consistent concept of what it means for a machine to be the same machine. Is it the name, the IP address, the physical hardware, etc... Just looks at what a mess Micro$oft has made of it with their software activation junk. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
