Best Way To Fix Core Data Migration Error

I have an application which uses core data and I have set up lightweight migration. When you first create the app xcode generates default methods. The persistentStoreCoordinator getter calls the abort() method and it says it should be replaced in a shipping application. I think the best way for my app to handle this failed migration would be to completely reset core data and then reload all the info. Is this the best method and if so how would I go about doing this?
