Your hosting plan must allow another domain before Plesk will offer this action.
Steps
- Open Websites & Domains.
- Select Add Domain.
- Enter the registered domain name.
- Choose Website hosting and confirm the document root.
- Add the domain.
- Point the domain's DNS to the hosting service, then upload the site into its document root.
If Add Domain is missing or Plesk reports a limit, the current plan has no free domain slot. A domain added in Plesk is not automatically registered.
