Hello, the best way to upgrade would be to use the online configuration tool and generate a new config for RRF3. If you already have an existing config set that was created with the tool previously you can load up the config.json file from your old config set and then switch it to the latest 3.x version and that should get you most of the way there, though you will likely need to manually adjust some fields in the tool for things that didn’t exist in RRF2, and if you have any customized special functions setup you will need to manually port those over as well. https://configtool.reprapfirmware.org/St... if you have any specific questions please use the support forum https://forum.duet3d.com/

There’s no reason you can’t. Please create a thread on the forum to get some guidance. It’s probably something pretty simple.

Yes USB power and LAN connection is a good way to start.

Perhaps you should create a forum post for more detailed assistance. https://forum.duet3d.com/
