Need help with transferring all DNS zones to a new server

Hi,

I have transferred all my cpanel accounts to a new server and now I'm ready to get rid of the old box. I currently have it setup so that the old server is a secondary DNS server and my new box is a master. old server is configured with dns111.domainname.com & dns112.domainname.com and the new box is setup with dns1.domainname.com & dns2.domainname.com. I want to eliminate the dns1 & dns2 from the new box and make it dns111 & dns112 so that it can take over the old box completely.

Can anyone help?

Thanks!
