Question

Is the High availability Supported between two different Firewall Platforms?

Palo Alto Networks devices only support high-availability between 2 identical devices.
If different Palo Alto models are connected in the same HA Pair, Error message is displayed and the device goes to suspended state

HA Group 1: Peer device platform model not matching; going to Suspended state.

If HA1 is connected between two different platforms, both nodes will go into a suspend state. To recover, disconnect the HA1 interface and reboot the device.
