Give the customers a customized mail telling them what they'll need to
change, and a deadline, if they don't make it, that's their problem.
Keeping things updated, in parallel, could be tricky, depending on
what they're doing/how they use things.
As previously suggested, you could proxy (in your httpd) from $OLD to
$NEW, maybe using something like migrated.client.hostingco.tld as
their new hostname, until they've sorted things out).
It might be useful to create a spreadsheet or similar for sites
migrated, and when there's been something done, so you can send
reminders, maybe when there are 15days, ten days, five days, two days,
and a "you're holding us up now", and finally a "you're disconnected
now" mails (assuming ~45days to handle change-over, but giving
customers 30days). You could also look at your network traffic graphs.
Renumbering will almost certainly require the co-operation of
customers, so get them involved, give them deadlines, and if they
don't do stuff, that's their problem. When their sites/email/whatever
ceases to work, I'm sure they'll fix stuff/come complaining.
