Moving a DNS server to another IP 1

[veronicabend]

Hi!

I'm not very experienced in DNS setup, and this is what I need to do:

1 - I have a DNS server running on one computer
2 - I have another computer, where cPanel has been just installed

I need to setup the DNS server (ns1.something.net), which is currently running in the old computer, in the new one. Trying not to provoke a collapse in the sites which use this nameserver.

This is my idea:
1 - Configure the DNS server in the new computer
2 - Copy the zonefiles from the old computer to the new one
3 - At the registrar, change ns1.something.net to point to the new IP.

Any help you can provide about how to go with this process is much appreciated!! Once of my concerns is that I'm afraid that when I change the IP in step 3, the sites included in that nameserver might not be reached until it propagates.

Thanks!
Veronica

Your best bet would be to creat a cname(alias) for the new dns server 2 name and point to the old/currnet dns server 1 name/IP. This way you can assure that when you cut over to the #2 server you will still have resolution with #1. Promote the new #2 to primary and ensure operational parameters are in working order for a week or so before pulling the plug on #1 and removing the cname.
