It’s not possible to move a website subscription or payment between sites directly. However, you can cancel the site you don’t need and upgrade the one you want to use in its place. You can also move any associated domains or G Suite account. You can't move an Email Campaigns subscription to a different site.
For steps to cancel a site and start a new one, visit I upgraded the wrong site.
Before cancelling, review our website refund policy, which still applies when you cancel one site and upgrade another.
