Hello, We are planning to transfer an app to a different Apple Developer account and had several questions regarding Apple App Site Association (AASA) and Universal Links behavior after the transfer. We are specifically interested in the period immediately after the app transfer, but before the app has been updated under the recipient account. We currently support Universal Links through our Apple App Site Association (AASA) configuration. Could you clarify the following: After the app transfer, will existing Universal Links continue functioning for users who already have the app installed? Will we need to update our AASA file to include the recipient account’s new Team ID in order for Universal Links to continue functioning properly? If so, is there a recommended transition strategy for supporting both existing installed app instances and newly installed versions during the migration period? Any clarification on the expected Universal Links and AASA transition behavior during and after an app transfer would be greatly appreciated. Thank you.

Hello, I was planning to transfer an app to a different Apple Developer account and had a question regarding DeviceCheck behavior after the transfer. Currently, the app uses the DeviceCheck service with a DeviceCheck key associated with the transferring account. We are specifically interested in the period immediately after the app transfer, but before the app has been updated under the recipient account. Could you clarify the following: Will DeviceCheck validations continue to function after the app transfer using the existing DeviceCheck key and "iss" value associated with the transferor account? Or will DeviceCheck requests begin failing until a new DeviceCheck key is generated under the recipient account and our backend is updated to use the new "iss" value? Any guidance on the expected transition behavior would be greatly appreciated. Thank you.

Hello, We are planning to transfer an app to a different Apple Developer account and had several questions regarding APNs continuity and behavior after the transfer. We are specifically interested in the period immediately after the app transfer, but before the app has been updated under the recipient account. I’ve done some due diligence on this topic within the forums and found related guidance here: https://developer.apple.com/forums/thread/744468?answerId=776692022#776692022 My understanding from that thread is that the existing push notification credentials will become invalid after a short delay following the transfer, and that we would need to update our backend to use newly generated credentials from the recipient account. However, since things can evolve over time, I wanted to confirm whether that guidance is still accurate for the following scenarios. For users who already have the app installed and previously opted into push notifications before the transfer: Will existing APNs device tokens remain valid after the app transfer? Will these users continue receiving push notifications without interruption, assuming our provider infrastructure remains unchanged? For users who newly install the app after the transfer: Will we need to migrate to a new APNs authentication key or certificate associated with the recipient Apple Developer account in order to successfully register for and send push notifications to those users? For users who restore or migrate the app to a new device (for example, via iCloud Backup restore or device-to-device transfer): Will push notification registration continue to function normally after the app transfer? Will those app instances need to re-register and obtain new APNs device tokens associated with the recipient account? To support this scenario, would our provider infrastructure need to migrate to and use a new APNs authentication key associated with the recipient account? Any clarification on the expected APNs transition behavior during and after an app transfer would be greatly appreciated. Thank you.
