The following steps were followed:


Log into WHM and go to Basic cPanel & WHM Setup
Change the Primary IP here with the option that says "The IP address (only one address) that will be used for setting up shared IP virtual hosts"
Note: This might not actually be necessary.

Log in to SSH, and do the following:

Edit /etc/sysconfig/network-scripts/ifcfg-eth0
Change the IPADDR and GATEWAY lines to match the new IP and Gateway for the new ip
Edit /etc/sysconfig/network
Change the GATEWAY line here if it does not exist in the ifcfg-* file.
Edit /etc/ips
Remove the new primary IP from this file if it is present
Add the old primary IP to this file with the format <IP address>:<Net Mask>:<Gateway>
Edit /var/cpanel/mainip
Replace the old primary IP with the new primary IP
Edit /etc/hosts
Replace the old primary IP with the new one if needed. The hostname's dns will need to be updated too
Restart the network service to make the new IP the primary
service network restart
Note: You're probably going to be disconnected at this point, and have to log in to ssh using the new primary ip.
Restart the ipaliases script to bring up the additional IPs
service ipaliases restart
Run ifconfig and make sure all IPs show up correctly
Update the cpanel license to the new primary IP
Verify you can still log in to WHM and there is no license warning

===========

IP migration was done with each new IP, but all the sites are saying that the DNS server are not responding....

Any advice no this matter?
