You need to uninstall the game first

But if you don't export your save you will lose it

To do that follow those steps:

1.Open your old game.

2.Main menu => Load => To File

3.Move the file where you want to.

4.Uninstall the old version

5.Install and open new game's version.

6.Main menu => Load => From File(And select the exported save)
