You can easily install the necessary updates and even upgrade your Parallels Plesk Panel to the latest available release using the Updater function within your Parallels Plesk Panel.
To update your Parallels Plesk Panel:
The Parallels Plesk Panel connects to the Parallels official Parallels Plesk Panel 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.
You can also install all necessary updates by using external Parallels Plesk Panel Auto Updater utility.
To upgrade your Parallels Plesk Panel via Parallels Plesk Panel Auto Updater:
Your selected updates will be first downloaded and then installed. Follow the instructions of the Installation Wizard that will guide you through the installation process.
Depending on the importance of installed updates, Parallels Plesk Panel might prompt you to restart your server. It is highly recommended to restart the server, otherwise your Parallels Plesk Panel might not work properly.
Notes on updating procedures:
When upgrading to a new Parallels Plesk 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 components, 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 on the server's hard drive.
All Parallels Plesk Panel operations are suspended during the installation of Parallels Plesk Panel components that affect the Parallels Plesk Panel's core functionality.
