This area of WHM lets you copy move accounts from one server to another.
Copy an Account from Another Server — This feature enables you to copy an account from a remote server to your web server. You will need to know certain information about the remote server to use this feature.
Copy an Account from Another Server with Account Password — This feature will attempt to copy an account from a remote server without using the root account. However, this feature is only intended as a last resort. If the remote server does not have a working copy of Perl, have CGI enabled, and have an unmodified cPanel configuration, it is unlikely that the transfer will succeed. You should not attempt to transfer accounts greater than 250 Megabytes using this feature.
Copy Multiple Accounts/Packages from Another Server — This feature will attempt to copy multiple accounts and packages from a remote server. This can be useful when a reseller would like to move a number of accounts from one server to another.
Review Copied Accounts — This feature allows you to review any accounts that have been copied to your server.
The swapip Utility — This utility allows you to update an IP address in a zone record via the command line using 4 parameters.
