I'm in a similar situation - our primary DNS machine (known to the world as ns and ns2 is going to be decommissioned - I've deployed a replacement machine in a different data-center, and need to migrate the DNS records from the old machine to the new, then point the ns and ns2 records to the new ips this machine is on.

I have a two part problem I think...

1. migrating the records - the old machine is a RAQ3 and the new is RAQ4i
2. handling the switch over from 2 old IPs for ns/ns2 to two new ones.

You appear to have hinted at an additional issue - perhaps I'm missing something here - but you say not to have a second primary DNS - we setup each of our customers across ns/ns2 on one machine and ns3/ns4 on another - the records can be identical on both machines if the site is hosted on a third, or they are slightly different if the site resides on either of those two physical machines - what is the problem you are hinting at here?

I tried looking got the script that Gerald posted a link to - but it's not working.... I'm off in search of the sun variants - so far, no joy.  If anyone has a link,or tutorial, or simply words of advice on this transfer, I'd love to hear them, as I too don't want to manually re-enter all the DNS information from a very busy DNS server to a new replacement!

thanks
