Introduction

This guide describes how to upgrade the Fortinet devices in your network when you have two or more different devices that belong to a Fortinet Security Fabric. By using this guide, you make sure that devices are upgraded in the proper order, using compatible firmware versions.

Because the upgrading procedure can disrupt your network traffic, it's recommended that you perform upgrades to the Security Fabric devices during a maintenance window.

Note

Before upgrading a device, review the release notes for the new firmware version. Release notes are available in the Fortinet Documentation Library.

For information about firmware compatibility, see the Fortinet Security Fabric Compatibility Matrix - FortiOS and Fortinet Security Fabric Compatibility Matrix - FortiSandbox.
