Re-importing 2.6 project to 3.0 gives you error?

Unity Engine
1

Hi! I’ve been working my project using unity 2.6.1f3 via some C# and Javascript, and today I’ve heard very delightful news that Unity3 is finally out!

So I downloaded unity3, installed it and opened my old project by it. It asked it has to upgrade the project so I agreed - and when I played my project it gives hell lot of run time error!

I’m asking following questions because these might be causing problems, so here it goes:

  1. Is there any known issues/problems regarding importing old project into 3.0 project?
  2. Are they any unsupported functions or grammar in C# or Javascript used in Unity3 (compared to 2.6)?
    (Especially Socket scripting part)
  3. I’ve heard that Unity3 supports IME but Monodevelop still doesn’t. I have used some Korean in my script as comments, would that cause problems?
  4. My project is a network game, and I’ve build the project on server side by 2.6 and I’ve built my client side project by 3.0. would that cause problem? (The problem we are suffering now is nothing to do with this question, though.)

  1. no, aside of the requirement that some stuff needs to be ported because its no longer supported, present or working different, nothing is known

  2. Various ones as unity has changed and the mono under the hood is totally different.

  3. that should not directly cause problems but with the change of physx in unity 3 you might want to reconsider that if you use physics of any kind etc

Regarding question #4, this was what I was told (haven’t tested it yet): http://forum.unity3d.com/threads/61496-Will-2.6.1-networking-work-with-3.0-networking

About 2.6 → 3.0, there’s this: http://unity3d.com/support/documentation/Manual/HowToUpgradeFrom2xTo3x.html
