[Twitch] Unreal Engine 4.1 Tour - Apr. 24, 2014

Read this about the new 4.1 release:

Upgrading C++ code projects
You’ll need to recompile the C++ project for the new version of Unreal Engine
Locate the .uproject file in your game’s folder, and right click on it. (on Mac, you can also Command + Click)
Select Switch Unreal Engine Version -> 4.1 (on Mac, this is in a Services menu)
Right click to generate new C++ project files, then recompile your game normally.
Note: Some C++ APIs may have changed between versions, which can cause compile errors. Read the API Changes section for more information.

Now correct me if I’m wrong, but I think applying the above steps would make the project unable to open/compile with 4.0 version of the engine.

If that’s the case, is there a way to make a duplicate of the project and then upgarde the duplicate, so the older folder is still able to be opened by 4.0 while the new one is for 4.1 . I know we can make a copy of the folder, but isn’t going to be some conflicts, because of the same name and IDs?

And if it is, is there a way to resolve the conflict, even by hand?

Thanks guys.
