Before You Begin
Before you install this release, make sure that you have:
lA supported WatchGuard Firebox. This device can be a WatchGuard Firebox T Series (except T20, T40,
T80) or Firebox M Series device. You can also use this version of Fireware on FireboxV and Firebox
Cloud for AWS and Azure. We do not support Fireware v12.2.x or higher on XTM devices.
lThe required hardware and software components as shown below. If you use WatchGuard System
Manager (WSM), make sure your WSM version is equal to or higher than the version of Fireware OS
installed on your Firebox and the version of WSM installed on your Management Server.
lFeature key for your Firebox — If you upgrade your device from an earlier version of Fireware OS, you
can use your existing feature key. If you do not have a feature key for your device, you can log in to the
WatchGuard website to download it.
lIf you are upgrading to Fireware v12.x from Fireware v11.10.x or earlier, we strongly recommend you
review the Fireware v11.12.4 release notes for important information about significant feature changes
that occurred in Fireware v11.12.x release cycle.
lSome Known Issues are especially important to be aware of before you upgrade, either to or from
specific versions of Fireware. To learn more, see Release-specific upgrade notes.
Note that you can install and use WatchGuard System Manager v12.x and all WSM server components1with
devices running earlier versions of Fireware. In this case, we recommend that you use the product
documentation that matches your Fireware OS version.
If you have a new Firebox, make sure you use the instructions in the Quick Start Guide that shipped with your
device. If this is a new FireboxV installation, make sure you carefully review Fireware help in the WatchGuard
Help Center for important installation and setup instructions. We also recommend that you review the
Hardware Guide for your Firebox model. The Hardware Guide contains useful information about your device
interfaces, as well as information on resetting your device to factory default settings, if necessary.
