@F5Team I have never had the opportunity to test this but at face value it seems like it could work because the devices are almost identical with minor differences. Now I do know that F5 hasn't released an article on doing cross platform HA so I doubt it will work but it's worth a shot. Just make sure you backup the configuration of each device along with the master-key of each device if by chance something goes wrong and things no longer work. UCS backup of each device, not just going into the device and doing a "show running-config" for a backup.
The article below states that you can have HA between different hardware platforms or between virtual and hardware platforms, I and my colleagues have done this several times in the past but I couldn't remember if I have done it for an Active/Active scenario, but I think it should work though.
