Upgrading multiple firmware images on FortiGate
When using FortiManager to upgrade firmware on FortiGate, FortiManager can choose the shortest upgrade path based on the FortiGate upgrade matrix. In a multi-step firmware upgrade, each upgrade is a subtask.
You can use the FortiManager GUI to review the shortest upgrade path. You can also use the CLI to view and check the shortest upgrade path for a managed device by using the diagnose fwmanager command:
# diagnose fwmanager show-dev-upgrade-path 318 6.2.0
device FWF61ETK18003595(318), platform FWF61E, upgrade path from 5.6.10-1677 to 6.2.0-866 is: [6.0.0-76 --> 6.0.2-163 --> 6.0.3-200 --> 6.2.0-866]
It is recommended to also check that the upgrade path for FortiGate reported by FortiManager matches the upgrade path reported on the Fortinet Customer Service and Support site for the FortiGate device.
In this example, the device ID is 318, and you want to upgrade the device to FortiOS 6.2.0. The device is currently running FortiOS 5.6.10 build 1677, and the shortest upgrade path to FortiOS 6.2.0 is displayed.
To upgrade using the GUI:
- Go to Device Manager > Device & Groups.
- Select a device, and from the More menu, select Firmware Upgrade.
The Upgrade Firmware dialog box is displayed.
- In the Upgrade to box, select an image, and click OK.
The Upgrade Path Preview dialog box opens to let you review the upgrade before continuing.
- Click OK to start the upgrade.
FortiManager starts the upgrade. Each upgrade is a subtask.
When all the subtasks reach a status of 100%, the upgrade completes.
- When the upgrade completes, click Close.
