I have read the two Apple documents that pertain to transferring an app, but they go a little over my head, especially the user migration process.
What is the user experience if I do not migrate users and simply transfer the app without handling this? Assuming the app handles expired authentication correctly, will they simply be asked to sign in to the app again and all will be well? Or will the user ID be different, meaning that "signing back in" will actually create a new account?
In other words, is the user migration process only intended to minimize user inconvenience by maintaining logged-in sessions, or is it essential for user accounts to remain tied to their data?
Thanks in advance for any advice.
