Another thing you could do would be, now that you have a project with migrated things in it, is to just copy that folder to a new folder (named whatever your new project is), then change a couple .ini files to match the new folder name (GameName in DefaultEngine.ini, ProjectName in DefaultGame.ini … both in the project/Config directory) … no need to migrate to a new area… In the default game ini there is also a project ID that you can recreate on the edit->project settings page (top set of options, above the Engine stuff where you define inputs, etc).
Handy if you want to scrap a project and start over, or once you flesh out certain things like movement, sky dome, weapons, etc etc… that you want to use across -all- of your projects.
