FireCluster Upgrade, Downgrade, Backup, Restore, and Migration

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 v12.2.1 or higher, a backup image is saved automatically when you upgrade the Fireware OS for a FireCluster. In Fireware v12.2 and lower, we recommend that you save a backup image before you upgrade a FireCluster.

You cannot downgrade a Firebox to a version of Fireware lower than Fireware v12.1.3 Update 8, v12.5.9 Update 2, or v12.7.2 Update 2, based on your device model.
