Update to beta version of Unity 4 concern?

Hi Guys,

Thanks in advance for any help, I have bought a license for the beta version of Unity 4 and before I upgrade I would like to know what is involved in the upgrade and if anyone had any problems opening there unity 3.5 scenes in version 4?

Thanks for any help,

I can open my project in Unity 4 but there are a lot of errors to do with FBX importing and other issues so it’s been a non-starter for me (models are weirdly different sizes etc). Plus you must backup your project because if it doesn’t open then it’s trashed.

Unity Support are currently looking in to my issues - I imagine many projects are just fine - but make that backup and be warned.
