A little tip. If you try to move an account from one server to another server, but every time you do it the account's ip get's changed to 216.40.250.20 in the DNS zone... do this:

In the destination host's WHM, Server Setup - Edit Setup, make sure the "Main Shared Virtual Host IP" is set to the ip of the server. By default, it is imaged as 216.40.250.20 and apparently doesn't get updated even after to change other settings about hostname, etc.
