My scenario is that I have been developing an iOS app under my personal AppleID and provisioning a bunch of test devices to involve others in the testing. As we are close to rolling out this app, we plan on publishing it using a corporate AppleID. So when the app certificates are be created in the provisioning portal, they will necessarily be under a new AppID.
So the question is: when I rebuild my app with this new AppID and deploy it to existing testers, will they have access to the documents on their device that had been created by the previously-built app? If not, then how do I go about migrating them to the new app without forcing them to re-enter stuff they would have preferred to keep?
