You can easily install the necessary updates, control panel add-ons, and even upgrade your control panel to the latest available release using Parallels Plesk Panel Updater function within your Plesk control panel.
To upgrade your Parallels Plesk Panel or update its components:
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 the 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 panels core functionality.
If you need to install a new license key after upgrading, then you will need to open a Support ticket with us requesting a new license. Please specify the version you upgraded from and the currently upgraded version. A technician will retrieve the new license key and attach it to the ticket. You can then follow the instructions for installing your Plesk license key.
