Running comunnity edition on Netgate hardware
The reason I purchased a Netgate device was to have a clean open source solution. It appears the official release is moving away from that, which makes me a bit uncomfortable. Can I migrate my licensed Netgate SG-5100 to community edition? Is it possible to do this without reloading?
Yes, the 5100 should run CE no problems.
You should reinstall to do that but you can import your config from Factory.
