FireCluster Upgrade, Backup, and Restore
WatchGuard periodically distributes upgrades for Fireware OS and WatchGuard System Manager. To keep your network secure, WatchGuard recommends that you install the latest available versions of Fireware OS and WatchGuard System Manager for your FireCluster. If you use WatchGuard System Manager to manage your Firebox, you must upgrade WatchGuard System Manager before you upgrade the Fireboxes it manages.
In Fireware 12.2.1 and higher, a backup image is saved automatically when you upgrade the Fireware OS for a FireCluster. In Fireware 12.2 and lower, we recommend that you save a backup image before you upgrade a FireCluster.
