Does Testflight migration to iTunes Connect retain the same application icon and data?

Question

I'm wondering if TestFlight users will be able to retain their data (in Core Data and User Defaults) after I migrate my app to iTunes Connect TestFlight, or if their app will be totally reset? (or if it will install to a different application icon)

Thanks

Answer 1

I tried it and it looks like NSUserDefaults and Core Data are retained no problem, with the same app name. However, TestFlight did give me a warning that app data might be deleted, so there could be other circumstances where data gets erased.
