Users & Devices error after downgrade (downgrade error)

[dparra]

When downgrading FortiGate from FortiOS version 7.4.x and above, down to version 7.2 or 7.0, an error may occur where the "Users & Devices" dashboard section shows the name "Assets & Identities", which is the section name on version 7.4.x

This can cause a malfunction where no information is shown. To correct this, download a backup config file and replace this portion:

set name "Assets & Identities"
set vdom "root"
config widget
edit 1
set type device-inventory
set width 2
set height 1
next
edit 2
set type identities
set x-pos 1
set width 2
set height 1
next
edit 3
set type firewall-user
set x-pos 2
set width 2
set height 1
next
edit 4
set type quarantine
set x-pos 3
set width 2
set height 1
next
edit 5
set type nac-vlans
set x-pos 4
set width 2
set height 1
next
end
next

By this:

set name "Users & Devices"
set vdom "root"
config widget
edit 1
set type device-inventory
set width 2
set height 1
set table-visualization "charts"
set device-list-view-type "hardware_vendor"
next
edit 2
set type forticlient
set x-pos 1
set width 2
set height 1
set table-visualization "charts"
set device-list-online "online"
set device-list-telemetry "sending"
set device-list-view-type "interface"
next
edit 3
set type firewall-user
set x-pos 2
set width 2
set height 1
next
edit 4
set type quarantine
set x-pos 3
set width 2
set height 1
next
edit 5
set type nac-vlans
set x-pos 4
set width 2
set height 1
next
end
next

Load this config file to the FortiGate using the restore option, the dashboard option will now show under the correct name and work as expected.

Hi,

downgrade is not recommended on FortiGate.

Due to migration of settings forward in the upgrade, the migration backwards may not work as the old firmware file may not be aware of the newer settings.

As such, downgrade requires restoring from a backup configuration that was pulled from before the upgrade.

Best regards,

When you downgrade this mean either you've the configuration file of that firmware or not. If you've the latest stable configuration file then format FortiOS and re-flash it with that firmware and then restore the configuration file as per:

https://community.fortinet.com/t5/FortiGate/Technical-Tip-Formatting-and-loading-FortiGate-firmware-...

If you don't have the configuration file for the downgrade firmware thne you need to use forticonverter to convert the configuration file from newer firmware to older firmware as per:

1. One-time Forticonverter service portal (you need to register using the portal):

https://service.forticonverter.com/

2. Licensed version of Forticonverter for many conversions (search for FortiConverter Migration Tool):

https://www.fortinet.com/support/product-downloads

In all cases, the downgrade is only recommended as per the above and not directly from the FGT's GUI.

Hope this help
