All cPanel accounts have a primary domain name associated with them.
This main domain can only be changed by raising a Support Ticket.
When you submit your support Ticket you'll need to specify
the cPanel account username
the existing domain name
the new domain name you wish to use.
The cPanel username itself (your cpanel username) will NOT change.
Remember to make sure the new domain's nameservers are set to PHPFusion otherwise you won't be able to control the new domain's DNS records via your cPanel account.
Things to bear in mind
The domain must not already be assigned to a PHPFusion cPanel account
Because we operate a central DNS system, it is not possible for us to host the same domain twice on our network.
Therefore if the new domain name is the primary domain for another cPanel account, or it is parked or added-on to an existing cPanel account, then you will have to remove it before we can complete your request.
All existing mailboxes will be renamed following these rules ,
All existing firstname.lastname@example.org mailboxes for which there was not already a email@example.com will be renamed to firstname.lastname@example.org
e.g. if you have email@example.com and you DON'T have firstname.lastname@example.org, then after the change, all of the messages and folders in email@example.com will now be in firstname.lastname@example.org
All existing email@example.com mailboxes for which there WAS already a firstname.lastname@example.org will be REPLACED by the mailbox for email@example.com
e.g. if you have firstname.lastname@example.org AND email@example.com, then after the change you will find that firstname.lastname@example.org will contain the same content as it did when it was still a parked/addon domain.
You will lose the email from the old domain mailbox.
