I have a lite app on store which uses core data for data persistence, it would be nice if users could migrate their data to the full version of the app after upgrading.
I found this article but it talks only about SQLite databases.
I seem not to find any information about this no where.
Anyone an idea on how to do this ?

What is the meaning of ETL migration? ETL represents Extract, Transform and Load, which is a cycle used to gather data from different sources, change the data relying upon business rules/needs and burden the information into an objective data set.
Core Data is a framework that you use to manage the model layer objects in your application. It provides generalized and automated solutions to common tasks associated with object life cycle and object graph management, including persistence.
There really is no difference between SQLite and Core Data in this regard. Just copy the file you use as Core Data store as described in the article you linked to.
