i have had removed the game from my pc couple of times as back when updates were not as frequent an would still have saves remaining. as didn't do deep removeal of everything so kept saves.
So if you have say one version still on your device it will still have the saves from it.
only time when saves from one version to newer version not usable when its a major change to the games coding that requires you to restart.
as like when the first town was list of buttons for each location to now a map of where each house is an such. that was enough of change to make everyone restart
