Moving from ad hoc distribution to the store - will the current app be updated, or will the store version be installed as a duplicate?

Question

I've been developing an iOS app that will soon be distributed via the B2b store. My client has been testing it for a few weeks with an ad hoc build. I'm ready to launch on the store with minor bug fixes, but the app will be largely unchanged.

The app uses core data and my client has been entering information that they would like to see retained in the store version. My question is, if a user downloads an app from the store, will it behave as if the existing ad hoc install is updated, preserving the clients information, or will it be installed as a fresh copy?

The store app will have the same bundle ID as the ad hoc version.

Answer 1

If the adhoc version uses the same bundle ID as the store version, everything should remain the same. If the client accesses the store page of your app, it will appear as installed already. Your store version should be of a higher build so his adhoc version is updated by the system.
