Active Passive HA licensing with a Software SFV4C6 firewall

Hello there,

Thank you for contacting the Sophos Community.

In Active-Passive mode, only the Active needs the license.

I don't recall seeing a configuration of HA in 3rd Party Hardware, though. 

Regards,

So if I buy a XV4C6Z00ZZPCAA that should give me a 2nd SFV4C6 serial number so I can then load up a second SFV4C6 firewall and because they will be the same firmware and version it should allow me to configure them in Active Passive setup. 

What is ironic is I HAD them already setup in Active-Passive HA setup with this hardware but I was under an evaluation serial number for each of them and I could not apply a licensed subscription to that base evaluation serial number because it was a SFVUNL serial number. 

If you start a second virtual appliance, you can, before registering, in the wizard select "join HA". 

This option will generate a HA Serialnumberfor you. 

I'll give that a try.
