Upgrading the Panel

This chapter discusses the upgrade earlier versions of the Panel to the latest one on servers, be it Linux/Unix- or Windows-based.

To upgrade the Panel, use the Parallels Installer utility. The utility connects to the Parallels Updates server where the Panel packages are stored, retrieves required packages and upgrades them.

Important: Make sure you upgrade all installed components when upgrading to a newer version of Parallels Plesk Panel. This is required to avoid conflicts caused by outdated components.

The Parallels Installer utility is available for downloading from http://www.parallels.com/products/plesk/download/. There are several distributions of Parallels Installer created for different operating systems and platforms, so be sure to obtain the Parallels Installer that matches your host operating systems. Normally, Parallels Installer binaries are distributed under names in the following format: parallels_installer_v<installer version>_<build date>_os_<operating system name>_<operating system version>_<platform>.

Parallels Installer works in either via a Web graphical user interface or command line.

Important: Parallels Plesk Panel 10 employs a new business model. The essential business objects are converted automatically during upgrade, and you will have to do several steps yourself to complete switching to the Panel 10 model. For detailed information, refer to the document titled Switching to Panel 10.
