I can accept that, this is why I asked the list.

Now I am confused. The domain totallogic.com is registered with 
Register.com. We host the authoritative name servers for the domain.

Currently I have two Bind servers running at 65.124.104.25 and 
65.123.104.25 (ns[12].totallogic.com). I have three djbdns servers 
running at 65.124.104.30, 65.123.104.30, and 65.124.110.14 
(ns[123]auth.tls.net).

The changes I asked about would be the updates to my local records, the 
A records for the bind servers. If I go to Register.com and login to 
manage the name servers for domains we host, there is no place to put an 
IP, none, just a FQDN. (I remember domain name registration requiring 
IPs of the authoritative servers, but I have not registered client 
domains in over six years).

It seems to me if there was a place to change the IP of the name servers 
with the registrar I would change the IP there as well as my A record, 
but there is not. So as long as all of my servers provide authoritative 
responses for totallogic.com, it seems changing my local record is all I 
need to do. That and wait before turning off the old server. We wait 7 
days by policy, many client's windows servers refuse to give up there 
cache, so we wait longer than the TTL.
