Hello,
I have finished a game and released it for the PC with Unity 4 Free License. After some time I thought it would be nice to port the game to android platform but I dont own an android license for unity 4, but I do have one paid license for unity 3.x. My project is already finished and all I would need to do is tweak the input scripts and change most of the models to lower their poly count. But my question is can I import my project into unity 3 to be able to compile it for android or is there a kind of cheaper upgrade if I have an existing android license. ( I bought the license a week before unity 4 was announced so Its still kinda fresh and used only on one game )
