Here's a link regarding the firmware upgrade of a standalone FortiGate firewall using the web GUI.
To check the current FortiOS firmware version (in FortiOS 6.x), go to System > Firmware > Current version: FortiOS v6.4.6 build6083
You can perform a firmware upgrade either online via FortiGuard or manually (offline) which I've performed in this post. My target firmware is 7.2.2 build1255.
Always
check the upgrade path using the Fortinet Upgrade Path tool and release notes. Select Current
Product from the drop-down option (FortiGate-40F) > select Current FortiOS
Version: 6.4.6 > select Upgrade to FortiOS Version: 7.2.2 > click GO.
The Recommended Upgrade Path is: 6.4.6 build 1879 > 6.4.8 build 1914 > 7.0.7 build 0367 > 7.2.2 build 1255.
Since I'm already on firmware version 6.4.6 build 6083, I upgraded first to 6.4.8 build 1914.
Go to FortiCloud
> Support > Downloads > Firmware Download. You'll need to create a login and valid support contract in order to download the firmware.
Go to Download tab
Select the v7.00 directory folder.
Select the 7.2 directory folder.
Download
the firmware according to FortiGate platform/model. In this case I used a FortiGate 40F.
Use the get system status command to verify in CLI.
