No, your saves are automatically detected by the new version - just download, extract (and install if you're on Android) and play! :)
If you're on Windows, Linux or Mac you can delete the old folder no problem. If you're on Android, however, DO NOT DELETE THE GAME or you'll lose ALL your progress (Google won't let me utilize their cloud saves because game is naughty :P )
