It is not possible to directly change the domain name of any workspace that has been created. If the workspace you created needs another domain name, a good solution is to duplicate the workspace and create an identical copy with a different name and domain.
Tip: to free a domain, you can delete the workspace. Please note that a backup is retained for 30 days, so the URL is not released immediately. If you have questions, please contact us at [email protected] or via chat when you're logged in to a workspace as an admin.
