Attention - Existing email addresses will also be renamed. - If you have installed a web application for the domain via Plesk, the application's configuration may be automatically changed by Plesk. Therefore, please create a backup of the configuration as a precaution.
You can find the instructions here.
The domain can be renamed independently via Plesk in the Websites & Domains menu.
1. Click on the domain name to access the hosting settings.
2. Now you can freely adjust the domain name under Domain Name.
Please also note that renaming does not affect the preview address. You can request an adjustment of the preview address via our support form or alternatively create a domain alias.
