How can I connect a domain to a different Wix site?
You can reassign your domain name to any of the sites within your account. However, in order for a site to be assigned a domain name, it needs to have a premium plan attached to it. Therefore, if you only have one premium plan, please transfer the premium plan to your new site. Alternatively, you can purchase a second premium plan for the new site.
To reassign a domain name (after transferring the premium plan): Sign in to your Wix account > hover over Subscriptions > click Domains > next to the relevant domain, click Manage.
Under Domain Summary, under Domain Connects to, click Change > choose a Wix site to connect your domain to > click Save > click Done.
