Please find the steps to transfer the accounts from cpanel to cpanel.
To transfer account you should have root access on both servers. Because to transfer account you need every thing to backup for transfer including Cpanel User / Pass (Same), Website, Database, Emails, Users, Stats etc.
The thing i like about CPanel is it will transfer accounts 100%, you will not miss any single think related to your accounts. This method implies on VPS’s and Dedicated Server where you can access WHM (Web Host Manager) or root shell.
Lets consider we have two servers A and B. Server A is the old server with two accounts and Server B is new server to which we will transfer accounts.
Server A = 192.168.0.1
Server B = 172.20.0.1
1 Transfer using WHM
Login to Server B WHM using following url
where 2086 is the port on which WHM is running.
In the middle page select Transfer and then on Transfer page select Copy multiple accounts/packages from another server.
It will open new page to put info of the Server through which you are going to transfer i.e Server A.
Remote server type is (WHM version will be auto detected on multi account
copies): leave as it is
Remote server address (ip address or FQDN): put server hostname or IP Remote SSH port: 22 is the default, if you have changed ssh port on old server use that one here.
Do not compress transfers (cPanel 10.8.3+ required on both ends): leave at it is Turn off SSL (cPanel 11.23.6+ required on both ends): leave at it is Allow override*: leave at it is Login as : Choose USER if you have sudo or direct root login are not allowed. Else select ROOT (recommended) Select authentication method: Choose Password here, if you are using Public Key then you have to upload Key using Security -> Manage SSH Keys to use here.
Root Password: put root password here
After putting all information above click on Fetch Account List. In few second you will see list of accounts from Server A to transfer. Select the account using check boxes to copy, if need to copy all select Select All to check all accounts. When done with select click on Copy. (Beware once you click on Copy dont close browser or click on Back button).
You will see account transfer log on your browser and when finished it will show nice summary about transfer.
