In RAI, you can detach a domain from the website where it's currently used, for example if you wish to use the domain on another website on the same account. You can also terminate the domain by changing its on-expire behavior.
See how
Detach a domain
To detach the domain from the website where it's currently in use, click the Manage button and select Detach from site from the dropdown. Click Apply to execute the change.
You can then attach the domain to a different website on the same account. While a domain is detached and a visitor tries to access it, their browser will show a 404 Not Found page.
Move the domain to another account
If you wish to use your domain on a different account in RAI, click the Move button next to the relevant domain, type in the Account ID you want it moved to, followed by clicking Move.
Terminate a domain
In case you or your customer no longer wants a specific domain, you can set the domain subscription to terminate once it reaches the expiry date. In the "On expire" column, click on Renew to change the status to Terminate. The domain will then terminate on the date specified in the "Expiry Date" column.
If you or the customer change their mind later on (before the domain has reached the termination date), you can always change the on-expire behavior back by clicking on Terminate.
