This question is a follow-on and clarification from this earlier post. I'd just like to confirm that after an App Transfer has been completed, whether there is any need for a new release to be cut? Judging from the prior post, my understanding is that a new release would not be necessary, and that all the existing versions of the app will continue to connect successfully with the APN servers. The only necessary update would be the server connection between the APN servers and the server used to generate notifications, with a new token or certificate. Is my understanding correct?

I'm in the process of preparing to receive an iOS App transferred from a 3rd party developer. It's unclear from the transfer documentation whether Push Notifications will continue to work after the transfer is complete. Could anyone provide clarity on when push notifications would begin to fail, if at all? For instance, immediately at transfer, after the first release from the new app store, or no failure until new APN tokens are created? https://developer.apple.com/help/app-store-connect/transfer-an-app/overview-of-app-transfer/
