Thank you for choosing Plesk.
This is the Plesk Installation and Upgrade Guide for Plesk Obsidian. In it, you will find instructions on how to install and upgrade Plesk on one or many servers, complemented with examples for the different platforms Plesk supports. The guide is structured so as to provide specific instructions to the different types of Plesk users based on their usual activities and needs. Most of the examples in this guide can be copied and pasted into the command line with no or minimal changes, which should be useful to users with no or little system administration skills.
This guide does not explain Plesk concepts or teach how to use Plesk. For that kind of information, please see Plesk Administrator’s Guide.

If you do not own a server, you can purchase a virtual server from one of the Public Cloud vendors (e.g. Amazon), and install Plesk there. For instructions, see Plesk Installation and Upgrade on Public Cloud Service.
The choice of license depends on the type of business you are running. If you need Plesk to manage your company’s or client’s web and mail server, you should go with Web Admin. If you are a web studio who also hosts their clients’ web sites, you may go with Web Pro.
The easiest way to upgrade Plesk to the latest version is to do it using the server configuration and management tools available to the Plesk administrator directly in the GUI. For instructions, see Upgrading Plesk Using Administrator GUI.
Note: Through Plesk GUI you can only upgrade to the following release tiers: General release (recommended), Early adopter, and Late adopter.
If you wish to have more flexibility in choosing a version and a tier for upgrading, use the interactive installer.
