Plesk offers a built-in WordPress Toolkit, which can be optionally used by customers to manage, secure and migrate WordPress content for their sites.

Plesk's WP Toolkit Documentation

WP Toolkit also provides options for Copying Data or Cloning:

Web Hosting - Clone/Copy of WordPress sites

Regarding the "Security" and "Security Measures" section:

• While this section of the WP Toolkit is intended to make your website more secure, in practice you need to assess each one of the suggested configurations individually. We have had many websites break as a direct result of applying all of them.
• There are little circled (i) information bubbles which further explain the idea behind each suggestion, and you need to cross-reference what they are trying to do with the suggestions in the official Wordpress Hardening Guide
• Example: Changing the location and file permissions on wp-config.php may seem like an obvious idea, but if you depend on a plugin that updates wp-config.php directly, it will break that functionality. Keep in mind that we provide an environment where each website is configured to be isolated from other customers.
• Always test these changes on your test site before applying to your production site. You have options in the WP Toolkit to not only apply the configuration changes, but also to revert them, and please remember to take backups before changing anything.
• Lastly, please keep in mind that the WP Toolkit is provided as a convenience to you as a way to assist in your responsibilities as outlined in the Division of Responsibilities section of our Terms of Use and echoed in our Wordpress Usage Guide
