Oh yeah, that's nice. So neither VPS's or the vsites need an IP address 
renumbering. It's just fixing the NAT, which keeps the changes all in one 
place, where a (more or less) easy search and replace should suffice. So 
that's just the NAT stuff and the DNS that needs to be messed with.

Oh oh. That's off to a good start then. :o)

Yeah, that's of course also an option. As a precaution you could also decrease 
the TTL of the DNS records a few days prior to the move. That way any DNS 
change that you make during the renumbering propagates a lot faster. I usually 
work with TTLs of 300 or 900 seconds during such phases, which is a hell of a 
lot shorter than the usual 3d validity of such records.

Sure, you have my number and I'd be glad to lend a hand. As always, Colin.
