Migrate settings from Surf SOHO to Balance 20(?)

I own a Surf SOHO MK3 that I don’t use the WiFi on anymore, and I am considering upgrading the Surf to a Balance 20. I’d like the Balance 20 to be configured identical to the Surf. Anyone know if I can just download the Surf’s configuration file and just upload that file to the Balance? Or do I have to configure the Balance manually to match the Surf? Surf has a lot of firewall rules and such I’d rather not have to put into the Balance manually.
