Upon IOS app switch or migration, what are the results if person didn’t improve app from app-store

We’re able to migrate the app from Developer-Account A to Developer-Account B, and we’re questioning what the impression is on customers who initially put in the app when the app nonetheless belonged to developer account A.

Are you able to clarify any facet impacts?

For instance: person Signal-In with Apple Id, does the worth of ASAuthorizationAppleIDCredential.person returned by AuthenticationServices change? Is that this .person worth associated to Developer-Account A or Developer-Account B?

func sendRequest() {
        let supplier = ASAuthorizationAppleIDProvider()
        let request = supplier.createRequest()
        request.requestedScopes = [.fullName]
        let authorization = ASAuthorizationController(authorizationRequests: [request])
        authorization.delegate = self
        authorization.performRequests()
    }
    
    //AuthenticationServices delegate name again
    func authorizationController(controller: ASAuthorizationController, 
                                 didCompleteWithAuthorization authorization: ASAuthorization) {
        //Did get person identifier
        let credential = authorization.credential as? ASAuthorizationAppleIDCredential
        let person = credential?.person
        // did this person worth modified after App migration, When customers use older variations
    }
