I have an Enterprise application that I would like to put ino the App Store, and I have a few questions and concerns. Most importantly, I would like to use the same bundle ID for the store version so that when users go to the store to download the latest version of the app their device will recognize that the app is already installed and update. Is this possible, or will I have to use a different bundle ID and treat the store version as a separate app?
Posting Enterprise App in the Store
Two accounts can't own/use the same bundle ID. There is no mechanism that allows the store to update non-store apps.
