We are preparing to address the upcoming change to the Certification Authority (CA) for the Apple Push Notification service (APNs). We have a few questions regarding the necessary measures.
-
Is the change of the Certificate Authority (CA) related to APNs something that needs to be handled on the server that sends push messages?
-
In relation to the CA change, do we need to reissue the APNs certificate?
-
If we handle the CA change on the server side and the new CA certificate already exists there, is there no need to make any further changes?
-
If the server’s trust store already includes the new CA certificate, it seems that no additional changes are needed. Is it possible to verify right now that everything will function correctly?
