(Optional) Upgrading the firmware for the HA cluster

Upgrading the firmware on the primary FortiGate automatically upgrades the firmware on the backup FortiGate. Upgrading firmware causes minimal traffic disruption. Before upgrading firmware, always review the Release Notes first.

1. Click the System Information widget and select Update firmware in System > Firmware.
2. Back up the configuration and update the firmware from FortiGuard or upload a firmware image file.

   The firmware installs onto both the primary and backup FortiGates.

3. After the upgrade is complete, verify that the System Information widget shows the new firmware version.
