title: "Merging" Core Data Models
body: <p>Since its kinda hard to explain I'm gonna example it:</p>
  
  <p>Let's say Model V1 has an entity called Names, which in its first version has only a property called name; in the second version of the model, now Model V2, it also has lastName property. Since the new model schema has both name and lastName properties in it, it won't accept any SQLite(?) or Model without those properties. So what I want is try to merge the Model V1 into Model V2 matching fields according to MappingModels or any other kind of migration.</p>
  
  <p>So my question is, can I do what I just explained or do I need to iterate over all Model V1 properties and manually match them to the newest properties on the current model?</p>
