When we switched, we maintained our old connection for about two weeks to
allow us a comfortable window for the change. During that time, I installed
secondary NICs in both name servers, assigning IP addresses on the new
network to the secondary NICs (these new addresses then became the new name
server addresses used in our WHOIS records. Except for this commonality,
the two networks did not cross paths physically because the new network and
old network were on different routers, hubs, etc. I am not saying that this
need be the case for you, but you might want to do this if you have two
providers online like I did.
Anyway, this allowed my name servers to answer on both networks
simultaneously. This way, when I changed the IP addresses of my hosts
within my zone files, the world was fed the new host-to-IP mappings even if
they were still "dialing up" my old name server addresses.
I'm sure there are other ways of accomplishing this, but this worked for me
and the only downtime I had was the time it took me to assign new addresses
to the NICs, the zone files and the httpd. It was actually a rather
painless process.
Note: if the provider you are using for your new circuit is the same one you
were using before and your old circuit is gone, I see no reason why your
provider couldn't route your old addresses to your new circuit while you
make changes. In that case, you might be able to forego dual NICs. Also,
don't try to multihome your PDC if you are running an NT domain.
Hope this helps.
