You can easily install the necessary updates, control panel add-ons, and even upgrade your control panel to the latest available release using Plesk Updater function within your control panel.
To upgrade your Plesk control panel or update its components:
The control panel connects to the Parallels official Plesk Update server at URL http://autoinstall.plesk.com, retrieves information on the available releases, then analyses the components installed in the system and displays the lists of available releases and component updates. For each release a brief description of available operations is displayed.
Note: If you have a number of Plesk-managed servers and have set up a mirror of the Plesk Update server in your network (as described in Plesk 8 Installation Guide), refer to the section Changing Updater Settings to configure Plesk Updater to retrieve installation files from the local mirror.
Notes on updating procedures:
When upgrading to a new control panel version, you will be notified by e-mail of upgrade procedure start and end. The notification message will include the event log and a list of installed packages, if upgrade is successful. However, you may not receive any error notice if your mail server fails. In this case you can check for errors in the autoinstaller.log file located in the /tmp directory on the server hard drive.
All control panel operations are suspended during installation of the so-called "base" packages that affect the control panel's core functionality.
If you need to install a new license key after upgrade, refer to the Upgrading Your License Key section. If you experience any problems with installing a license key, please contact firstname.lastname@example.org.
