I would like to use or convert NXT-G 2.0 programs for use with the new EV3 software. Is there an easy way to convert them besides just building them from scratch in the EV3 environment?
Unfortunately there are no shortcuts. EV3-G can not open programs written in NXT-G.
9.5 I have a LEGO MINDSTORMS NXT2.0 (8547) set; will there be an upgrade/conversion kit from NXT to LEGO MINDSTORMS EV3 (31313)? No, but LEGO MINDSTORMS EV3 offers backward compatibility to NXT. You can therefore use your NXT Intelligent Brick together with Intelligent EV3 Bricks in many situations. However, if you want the full benefit of LEGO MINDSTORMS EV3, you will need to transition to Intelligent EV3 Bricks.
