I was developing an iOS app for a few months and now my client wants to publish the app to his developer account. In the development process we were using Testflight to test it and I've put it on our developer account.
The situation right now look like this: we were using Firebase and Push notifications so if I change the bundle identifier for client submission it will not work properly.
What should I do to upload an app with the same bundle identifier from another developer account? Should I delete App ID from our account and then try to make certificate on the client account?
