Upgrade the CoreData in Existing Application when installing the new version of application

Question

Upon installing the new SDK into our application, I attempted to run the app, overwriting an existing application. I received an exception, the relevant stack trace of which is below:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason:

This NSPersistentStoreCoordinator has no persistent stores. It cannot perform a save operation.

But when i tried after uninstalled my application it is worked fine. I don't want to uninstall whenever i installing the new build what is the solution for this?

Did you make any changes to your Entity? – user523234 Sep 19 '11 at 10:22 — user523234, Sep 19 '11 at 10:22

You need to support Data Migration. See this related question: I keep on getting “save operation failure” after any change on my XCode Data Model

and the relevant Apple docs: Initiating the Migration Process

I is because you change the Core Data , maybe you add/modify/delete some entities, you need tyr the Data Migration , or delete it.
