Upgrading the firmware on the primary FortiGate automatically upgrades the firmware on the backup FortiGate. Both FortiGates are updated with minimal traffic disruption. Always review the Release Notes before you install new firmware.
- Click the System Information widget and select Update firmware in System > Firmware. 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.
After the upgrade completes, verify that the System Information widget shows the new firmware version.
