Hi, I am currently working on an App Transfer from Company A to Company B but can't find any documentation about what happens to existing Siri Shortcuts working via App Extension intents. I have separated the rest of the post in 2 sections: one what summarizes my current understanding and the other with some questions and hypotheses. It would be great to have either someone from Apple to answer that, or someone else share their experience and possibly some documentation that I might have missed. To my understanding, when a new Shortcut is created, it stores the BundleID of the App and of the App Extension to find the application that will execute it afterwards. If I uninstall the App, I can see a message in the Shortcut app that says "This action requires APPNAME but it may not be installed", but I know that after transferring the app the BundleID doesn't change completely, only the team part does. However, it is not possible to test that as this change cannot be done in xCode as far as I know. Another part that seems to play a role here is the info.plist file, but in my situation, there are no entries related to the BundleID. All that being said, I am wondering: Is it possible to perform an app transfer and keep previously created shortcuts working? Is it possible to test this kind of things without having to perform a transfer? I haven't found a way to change the team part of the Bundle ID Is there a place in the documentation that takes care of those things in depth?

Hi all, I am in the process of preparing for an app transfer, and have sign-in with apple enabled. I have read the documentation thoroughly and multiple times, yet there are a few things I'd like to have a confirmation about, before taking the leap and risking that some users might experience any issues. If I understand correctly, after the migration if a user performs a sign-in with Apple, they will send an access_token that differs from the one they were sending when the app was assigned to the old team. In case I didn't take any action that means that my system would think this was a new user given the access_token has never been seen before, and therefore it will create a new user. Is that correct? Ok, so if that assumption is correct, I'd like to have a confirmation also of the way I intend to fix this, since we're doing an internal transfer and the database is going to be the same. I would get a TransferID for all users in my database that have used sign-in with Apple (I have already done that for one of my test users, successfully). After that, I will start the transfer, and accept it from the other team. Once that is done, I will call the migrationinfo endpoint from the other team, getting all the new access_tokens related to the transfer ids. With that information, I will update my databse, adding a relation from the new access token from team B that points to the same user as the access token that was given by team A, and I know which one it is because of the TransferID. Does that make sense? Would it work? I'm not a fan of messing with the login logic (having a look at transfer_ids, looking for matches, and so on), especially because there doesn't seem to be a way to test this. I believe the only risk is that a user might login after the app has been transferred but before I can upload the new access token to the database, but we can handle these (few, hopefully even zero cases) via ticketing. These are the resources I have read so far: https://developer.apple.com/documentation/technotes/tn3159-migrating-sign-in-with-apple-users-for-an-app-transfer#Preparing-to-migrate-users-for-an-app-transfer https://developer.apple.com/documentation/sign_in_with_apple/transferring_your_apps_and_users_to_another_team#3546291 https://developer.apple.com/documentation/sign_in_with_apple/bringing_new_apps_and_users_into_your_team My last question is: how can I test this before going live? Do I really have to just implement changes/update the DB and then go live, hoping that it will all work? Can't I do some sandbox transfer or anything like that? Even just creating like a "clone" of my app and transferring this one would be a huge boost for the confidence of this big leap. Thanks in advance.
