Updating the application, inserting data into coredata while saving user data without changing the model

Question

I want to publish an update for my application.

I went in cycles on how to update the existing basic database of data which also stores the data entered by the user. All I have to do is update a couple of records and save the current user data. No changes are made to the model.

Thanks.

Write the code snippet that performs the upgrade and set the user preference value ( NSUserDefaults ) when you do this. Include this code in your new version by first checking the preference value.
