Migrate from Sqlite to CoreData

I have an application in which I am using Sqlite database till now. I want to upgrade application and deliver core data instead of Sqlite. I need to migrated existing sqlite db data to new core data db.

I am aware of the manual way in which I need to read data from sqlite DB and write it back to core data db once NSManagedObjectContext get ready for use.

I am looking for some automated way. Is there any way by which I can get rid of manual way and save my existing data from sqlite db to new core data db?
