The Problem: The UCS file contains the original license, which is invalid on the new RMA hardware, causing the "License is not operational" error and preventing the configuration (like pools) from loading.
Why C Works: The tmsh command with the no-license (or similar) option allows you to restore the configuration without applying the old license, enabling the device to become operational first.
Why Other Options Fail:
A (Remove from UCS): Manually modifying UCS files isn't supported and is risky.
B (Revoke): Revoking the license doesn't stop the UCS restore from trying to load it.
D (Reactivate): Reactivation happens after the configuration is loaded, not before, so it won't fix the restore failure itself.
Steps to Perform:
Restore the UCS using tmsh install sys ucs <filename> no-license.
After the restore, activate the new device's proper license via the Configuration Utility or tmsh.

Cuando se restaura un UCS en un dispositivo RMA, el archivo incluye la licencia del equipo original, la cual no es válida para el nuevo hardware (firma digital y dossier distintos). Esto provoca el error:
License is not operational (expired, digital signature does not match contents)
Para evitar este error, la práctica correcta es restaurar el UCS excluyendo la licencia y luego licenciar el equipo nuevo por separado.

I agree that the answer is C, because when you migrate to the new device, you have to give it a no-license so that it ignores the license of the previous device.

Only C, you want to upload UCS with no-license option, then activate NEW license in separate step
