We have deployed two versions of our in-house app to two groups of users. We want to have most users on the release version, but a few on the beta version. Right now we find that moving a user from one list to the other causes the app to be deleted and re-installed, losing their documents. We want to use the same app bundle id for both so they don't have to migrate their (quite large) documents between the two or use up double the space. Is there a better way to handle this?
