I haven't done any image upgrade on F5 devices and can't seem to find an answer. I am installing HF2 for version 12.1.2 on an HA pair of LTMs. Is there a need to enable the "Force Offline" on the standby unit which I am doing first? Much appreciated.

Yes, it’s good practice to force offline the unit you are about to upgrade. From 11.1.0 and higher, the force offline will persist after a reboot. It will prevent the unit to handle traffic, until you release it again. For more info see:
