Preventing FortiGates with an expired support contract from upgrading to a major or minor firmware release NEW

If the FortiGate support contract has expired, you will be unable to upgrade the firmware to a higher major version, such as from FortiOS 6.0 to 7.0, or to a higher minor version, such as from FortiOS 7.0 to 7.2. However, you can upgrade the firmware of a FortiGate with an expired support contract to a higher patch build, such as from FortiOS 7.4.0 to 7.4.1, to allow for security updates.

You can confirm the Firmware & General Updates (FMWR) contract expiry date in the System > FortiGuard page or by using the diagnose test update info contract command.

Example

The following example demonstrates what occurs when upgrading the firmware to a patch build and to a higher version with an expired license. The patch upgrade successfully upgrades the firmware from FortiOS 7.4.0 to 7.4.3. The major upgrade attempts and fails to upgrade the firmware from FortiOS 7.4.0 to 7.6.3.

To demonstrate the functionality of this feature, this example uses FortiGates that are running and upgrading to fictitious build numbers.

To upgrade the firmware to a higher patch build:

1. Confirm the current firmware version:

   # get system status
   Version: FortiGate-301E v7.4.0,build2303,230307 (interim)

2. Upgrade the firmware:

   # execute restore image tftp v743-B2400-GA-M_B230309_FGT_301E.out 172.16.200.55
   This operation will replace the current firmware version!

   Please wait...
   Connect to tftp server 172.16.200.55 ...
   ......

   Done.

3. Confirm the new firmware version:

   # get system status
   Version: FortiGate-301E v7.4.3,build2400,230309 (GA.M)

To upgrade the firmware to a higher major version:

1. Confirm the current firmware version:

   # get system status
   Version: FortiGate-301E v7.4.0,build2303,230307 (interim)

2. Upgrade the firmware:

   # execute restore image tftp  v763-B1505-GA-F_B234847_FGT_301E.out 172.16.200.55
