Then you must apply it using the apply command or via the Web GUI page [GENERAL] > [Whole Configuration] > [Apply New Configuration]. You can consult the change logs HERE.

Please note that some upgrades come with an update of the CacheGuard-OS License Agreement and it is important that you consult and accept the terms of the new license agreement.

Please note that some major upgrades require a re-installation from scratch and no patches are provided for them. Before reinstalling CacheGuard-OS from scratch, think of saving your configuration in order to reload it into to your freshly installed version. To save your configuration and its related files you can use the conf and file commands. If you prefer the Web GUI, you can use the [GENERAL] > [Whole Configuration] > [Load & Save Configuration] and [GENERAL] > [Whole Configuration] > [File Operations] pages. It is also important that you deregister your registered CacheGuard appliance prior to any re-installation (using the register command or via the Web GUI page [GENERAL] > [Registration & Subscription]).

CAUTION: applying a patch always comes with a risk of letting an appliance in an inconsistent state. That's why it is highly recommend to backup your system before applying a patch. You can backup your system using the system command line or via the Web GUI page [GENERAL] > [System Operations] > [Backup Restore].
