You must be logged into cPanel
In cPanel, scroll all the way down and select WordPress
Select the red button Clone
The compartment that is opened in the picture can be changed to select a subdomain and protection, whether IPv4 or IPv6 is used.
After this, you can enter your own domain that you have already established. You cannot move for WordPress to a page that has not been set up.
After this, you can still choose the end of the site (directory)
And when the new site name is set, select Clone Installation
Removal is much easier. On the WordPress front page, you just click on the trash can image.
