Upgrade FortiGate devices
All FortiGate devices in the Security Fabric must use the same firmware version. Upgrade the root FortiGate before upgrading the other FortiGate devices. |
- Go to System > Firmware. The new firmware is shown.
- Under FortiGuard Firmware, select Latest. You can also download firmware from the Fortinet Support website and then upload it manually to your FortiGate.
A notice may appear stating that there is no valid upgrade path for this firmware version. In this case, select All available instead and find a suitable firmware version for your FortiGate.
For more information about the upgrade path, use the Upgrade Path Tool.
- Select Backup config and upgrade. When prompted, select Continue.
- Save the backup of your current FortiGate configuration, in case you need to restore it after the upgrade process.
- After the FortiGate uploads the firmware and reboots, go to the Dashboard. Confirm that the System Information widget displays the correct Firmware.
For more information, see the FortiGate/FortiOS Release Notes and FortiGate/FortiOS Administration Guides.
