Uploading App to testflight from account A, then upload to AppStore from account B

Hi! I'm new to the whole publishing to App Store except for Testflight.

I am building a React Native Application that will be launched soon. The process is this:

We will use Apple Developer Account A to upload the App to testflight in order to test the application on IOS before we are ready.

When we are satisfied with the testing of the app, we will the begin the process of uploading the app to App Store. We will then upload the App via Apple Developer Account B (a new one).

Is this possible? Or will there be some certificate issues or identification issues? Maybe the app gets linked to Account A at first upload, and then can't be uploaded by account B?

Thank you for your time!
Hello Cevin,

You won't be able to register the same application on another account. The bundle ID has to be different.
However you may transfer the ownership of the app from one account to another if needed.
