Just reporting in, I'm running OPNsense on top of Proxmox, and had a nice smooth upgrade with no warnings or issues.
My setup is pretty simple, only custom config is some IPv6 settings for my ISP Aussie Broadband and some QoS settings for managing bufferbloat:

I've retested after the upgrade and all has come across nicely and still getting working IPv6 and good bufferbloat management:
