Solution

When trying to assign a Firmware Template to FortiGate, FortiManager may show the following error:

invalid template assignment - conflicting template assignment scope: device device_name, vdom root, firmware template [(null)] and [new_firmware_template_name]

This error is caused by an assigned and then deleted Firmware Template. The reference may still exist in the FortiManager database.

1. Take the configuration backup of FortiManager.

2. Run the following command on the CLI by specifying the ADOM name.

 3. Type 'y' to fix the scope-related database issues.

4. The assignment can be done after the CDB check.
