Will updated version to the Store remove old save state on device when installing to new version?

So let's say I have installed an app from the app store and it's version 1.0 and it used save states to save my personal best score, will that save state and score be removed when I install an updated version (1.1)?

I'm asking becuase I'm about to start using save states and need to know what way to save to keep the original save state through the different versions that might come, so it's not erased every time.
