    Well basically I need to take server from one server hotel into another.

    1. I need to change both nameservers and IP addresses from server.
    Will it be enaugh to change them via WHM?

    2. Host name - changing into
    Would that affect stuff that is inside server already by malfunction problems? How to get it right?

    3. I need to wait for 48 hours until they get published.
    How to make sure that they are actually working and wont be any problems later on when I take it into another server hotel?

    I have the same case:
    We are migrating from one data center to another (physically) and we will change the IPs and DNSs` IPs.
    So what we have to do:
    1. Make a script which will replace the old IPs everywhere (httpd.conf, /var/named and etc.)
    2. Change the IPs of the 2 dns servers in their zones
    3. Change the IPs in Child Name servers options in the domain registrar
    4. Change the TTL for every domain

    Is it enought to miss the downtime?
    Of course i cant prevent the downtime while I move the machines between the the 2 datacenters, but after that?
