Upgrade from 18.7.10

[raz]

Hello,

I've taken over a site using the OPNsense firewall, but I'm new to this, and I have a question regarding upgrading. Can I simply do an upgrade from the web GUI from v. 18.7.10 to the latest version without losing any settings or experience other issues?

I'd also like to know if there is anuwhere I can see if the firewall is running on a virtual machine or if it's on a physical machine?

Thanks,
raz
