Dear Users,
I've searched around without finding a solution for my problem.
Running a HA A/S cluster with 2 UTM120 and Firmware 8.3.
Since the devices are outside I don't want to upgrade to Firmware 9 and wait until license is over, and buy new hardware.
Now the second (slave) unit in the cluster is defect and I got via Sophos a new unit with Firmware 9.
My question is, can I send the unit to my client, plug in the HA cable on port 3 and power the unit up? Or will I have to downgrade the Firmware locally?
Thanks!
Michael
