Parallels Plesk Panel 9.X requires a new key. Your old key will not work for version 9.X.
If you are a lease customer with active Software Maintenance (SUS), you can use the auto-upgrade process directly from the Parallels Plesk Panel interface. The key will be automatically retrieved during this process. If the key is not retrieved, upgrade the key here.
If you plan to upgrade manually by downloading and installing a full distribution, you will need to upgrade your key to version 9.X before performing the upgrade. Upgrade your key here.
Automatic Key Update System — the Parallels Plesk Panel 9.X for Linux/Unix software includes an Auto-Update system for your Parallels Plesk Panel 7.5.4 license. Upon completion of the upgrade, Parallels Plesk Panel 9.X for Linux/Unix will automatically request your updated key. Provided communication is possible, the license will be supplied and installed automatically. If the upgrade is performed offline, not allowing communication to our licensing server, you will be prompted upon your initial login to retrieve your product license through Plesk’s License Manager.
IMPORTANT: Automated license management requires the license key running on the server to match the latest known version of the license in the licensing server. Customers where this is not the case must perform Manual Key Updates.
RPM distributions of Parallels Plesk Panel 9.X for Linux/Unix can be used for installation on clean servers or to Upgrade or Patch existing Parallels Plesk Panel 8.x or Parallels Plesk Panel 7.5.4 releases ONLY!
For details on how to make a proper backup prior to upgrading see the product release notes specific to your Operating System.
