Upgrading Unity 3 project to Unity 5
Upgrading project made with Unity 3 to Unity 5 loses all reference links.
Materials lose textures, Renders lose materials, GameObject loses MonoBehaviours etc...
Do I need to install Unity 4 and upgrade gradually (3 -> 4 -> 5) or is there some external tool or something?
not quite sure, so i'll write it in comments i think you HAVE to upgrade the project gradually, that's the easiest way
If you have time you could go backwards through the upgrade requirements and look for dependencies between steps here:
