This allows you to duplicate the contents of an existing site to a new site that you created under the package. First you must create a new site through the system (no matter its name) and leave the package empty (this is the package to which we will duplicate the site)

In the second step, go to the main package we want to duplicate, go to the Settings tab and click “Duplicate”

On the next screen, select the new package you created and click on clone to a existing website.

You can now see the duplicate site under the new link you created.
