How to move from single OPNsense to HA?

Hi all.

My Proxmox hosting the Firewall recently failed and I am striving for a more robust setup.

I think I generally understand the concept, but I am not certain how I would get there.

Today, my FW IP is 192.168.1.1 and the different VLANs have …10.1, …20.1, etc.

This is supposed to move to e.g. 192.168.1.2 and 192.168.1.3, and the original IP will turn into a virtual one.

I don’t want to loose my network with a heavy rework for too long since I usually have tons of questions in between and need to research 😂

Or can I just install the 2nd FW on 192.168.1.3, create the virtual IP and have this one as a drop-in replacement of the first one?

(Settings not synced automatically, I think)

Thanks
