Using keychain after App transfered and fixing App id prefix

I have the app using keychain, and I will transfer this app to a new account.

But after App transfered, app users will face the problem of losing access to keychain because of App ID Preifx change.

To solve this problem, I considered the solution that I change App ID Prefix to the previous ID after App transfered.

(App ID Prefix is changeable by submitting a request to Apple.)


I asked about this idea for Apple Support.

The Answer was "It may be possible, but we don't know the past record. So ask in the Apple Developer Forums"


Is there anybody who knows something about this problem?

Is this possible?


I need information.


Thanks!
