Much apreciated Arc! I'm gonna assume it's those kinds where you have to keep the old game and install the new game for the save files to transfer
(Spoiler, I am stupid.)
If you're on Windows, Mac or Linux then no - you can delete your old game before installing the new one and your saves will still transfer :)If you're on Android then yes, you have to keep the old game as the new version will overwrite and update it.
