ASA Active/Standby using physical devices and virtual firewalls

[vitumbiko nkhwazi]

Hello.

I have a network with three Cisco 5516 firewalls that have not been virtualized. We now want to introduce redundancy by implementing Active/Standby pairs for the firewalls. Can we use one 5525 ASA and virtualize it so that the standby firewalls are implemented as three virtual contexts in the 5525? in other words, can an active/standy pair be between a physical firewall and a logical firewall?

Regards.

@vitumbiko nkhwazi no, you can only establish an HA failover pair between devices that are the same model and software version.

No, what I know the HA need Software and Hardware match to run.
