I am just wondering if anyone can say that I can import 4.5 projects safely to 4.6? If not I will download it wen I finish my 2D game. EDIT: I think I lost Unity forever… help needed ASAP!!!
Save your project on an external device or at least a different location (preferably external). Then open the normal project not the saved location. Also save the setup executable of your current version of unity (assuming you still have it).
After that close it down and upgrade, chances are it’ll work OK but ultimately if want to use the new features then you’re going to have to upgrade.
If you don’t want the new features then the choice is easy, don’t upgrade.
