Hi,

I've got quite a lot of relationships so thought exporting and importing would be quite involved, migration seemed the easiest method, It have used migration when upgrading the data model in the past and it has been fine. I'll certainly google import/export methods.

The actual apps are almost the same, I just want to remove an error in the data model

Many Thanks

Amy

I've created a new data model changing the Idea.description to Idea.ideaDescription and created a mapping model to manage the change, however when I try to run it with the data file it says it is missing the persistent store, the same happens when I try to simply delete the Idea.description and create a mapping model as well.
