Steps to migrate Core Data databases for shipped iPhone apps

StackOverflow https://stackoverflow.com/questions/1262352

Question

What are the recommended steps to be done for migrating Core Data DB changes for updated iPhone apps already shipped?

Is there any prior step one need (should) have done before shipping a Core Data app?

Was it helpful?

Solution

Apple has published a guide with regards to this topic: Introduction to Core Data Model Versioning and Data Migration Programming Guide

If you find the guide hard to follow (and it can be), this SO post may come in handy too:
