Renumbering a larger network takes some significant time.  Software
packages tie license keys to IP addresses, software has IP addresses hard
coded, etc.  Each of these requires project management, finding downtime
windows, user announcements / user upgrades, etc.  In some environments,
12 months is actually a very tight squeeze when you're renumbering, even
in a fully DHCP-enabled environment for end users.

Don't underestimate the work required in renumbering for medium and large
end-sites.  It's not fun, and I have battle scars to prove it.
