    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?

    Hmm... it seems everything was done correctly, it was just a catching issue.

    Thanks
