How to redirect a subdomain to another domain?

Log into Plesk

Go to Domains > subdomain.example.com > File Manager and create .htaccess file (or open an existing one) :

Add the following content:

RewriteEngine On RewriteBase /
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301,NC]

Note: Here www.example.com is the domain to which the redirect is performed

Log into Plesk

Navigate to Domains > subdomain.example.com > Hosting Settings and click on the [change] button:

Change the Hosting type to Forwarding and set up the desired URL:

Note: Forwarding type does not support HTTPS: it cannot be served over HTTPS and will not be secured with a certificate.
