Installation and Upgrade Overview
The most common way of installing and upgrading Plesk is to use the Plesk Installer utility. This utility connects to the Plesk Updates server where the Plesk distribution packages are stored. It then retrieves, downloads, and installs Plesk. You can download the Plesk Installer utility from http://autoinstall-win.plesk.com/plesk-installer.exe.
For detailed instructions on how to use Plesk Installer, refer to the Deployment Guide.
For information about installing third-party software services on Plesk-managed servers, refer to Installing and Updating Third-Party Applications.
Installing Plesk in Virtuozzo Containers
If you operate in the Virtuozzo containers environment, you can use application templates for installing Plesk on containers.
When the application templates are installed on a Virtuozzo hardware node, they allow you to easily deploy the application on as many containers as required, saving system resources such as disk space.
You can download the Plesk templates using the command
yum install. For more details, see https://kb.plesk.com/en/115548.
For more information on installing Plesk on Virtuozzo containers, read the Deployment Guide, chapter (Advanced) Installation to Virtuozzo Containers.
Checking Potential Issues Before Upgrading to Plesk 12
If you use Plesk 9 or earlier and want to upgrade it to Plesk 12, you may encounter problems due to changes in the Plesk business model. In particular, it might be impossible to transfer some settings and business objects.
To efficiently anticipate or resolve the problems, we offer a tool called
plesk101_preupgrade_checker.php. This checks potential business logic issues with upgrading to Plesk 10 and later and gives recommendations that help you fix the possible problems related to transition of Plesk objects. You can download the tool and find descriptions of the report messages at http://kb.plesk.com/9436.
