Same model for HA to functional properly?

[LouisScaringella]

I understand that both firewalls should have the same feature licensing for proper failover, but has anyone implemented HA successfully using two different models? 5050 and 5020 for example? I know in the documentation it states both models must be the same.

Hi,

Ideally the HA would not establish with the change in platform per the software. With change in minor release of software version it should be fine to work for HA.

Thanks
