Chaning all IP address for one server

[JSD]

Our colo provider told us we have to change the IP address (we usually have 3 ip per server) what's the easiest/safest way to change all IP's of a cpanel server?

First lower your TTL for your name servers really low
The After you add the ip to the box you can use cpanel to change all of the IPs within WHM

I would also edit your zone template for future updates
