Assuming you are running cPanel and WHM on two servers, you can move domains from one server to another. You can also do special transfers with certain other software programs. You can do these transfers one account at a time using this procedure, or you can transfer multiple domains at once - refer to Transferring Multiple Accounts from another server for more information.
When transferring accounts, you should note that their may be some downtime for the site(s) being transferred. To minimize downtime, you can use DNS clustering to update the DNS zone files automatically. You will need to make sure that everything is properly set up before the account(s) is(are) moved. By properly setting up the server that will hold the transferred account(s) beforehand, you will have less problems and can minimize any chance of down time.
To access the Transfers Menu, click on Transfers, on the main screen of your WebHost Manager interface.
NOTE: To transfer one account from a WebHost Manager server with a username and password, refer to Transferring one account from a WebHost Manager Manager with a Password for more information.
