Do you want to change the domain name set as the main one for your hosting account? No worries, it can be done in a few clicks!
Make sure that the domain name, which you want to be the main one, is visible in the list at Hosting → Manage → Add Website:
If it’s not there, add the new domain using the Add Website button.
Go to Hosting → Manage → Set Main Domain:
Open the drop-down list and choose the domain you want:
Congratulations, you have successfully set a new main domain! 🎉
If you don’t need the old domain name anymore, you can delete it at the Add Website page.
The Set Main Domain feature simply renames your hosting account. It has no influence on website files
