I want to change the app ID prefix of my application to my team ID.Because the current app ID was created long time ago and it is not as same as my team ID.In this case, I have some questions.1. If I change the app ID prefix, the app ID of my App should be changed. When the app ID is changed, can the new version application (with the new app ID) and the old version application (with the old app ID) be recongnized as the same application? In another word, when user update new version application, will the old version application be overwritten by the new version application?2. In my application, I provide a Auto-Renewable Subscriptions by using in-app purchase. When I change the app ID prefix, can subscribe user keep his subscription status after updating the application to the new version?3. Can I change the app ID prefix by myself or I need to ask apple support to do this for me? Please tell me the procedure for changing the app ID prefix.ThanksFeng
