How to replace sqlite file with the new one if I use core data?

I am currently working on the app that is going to use database to store items. The first thing that everybody say, when it comes to store data in iOS is Core Data.

But, after few days of looking through tutorials and docs, I have a big question.

Let me explain architecture a little bit more. So we have a backend, where you can add items, also, we have iOS and Android application. I am creating a Core Data model for our database. What we want,is to check if there is update for database and download it. The problem is that we don't use JSON or XML, we are using the new sqlite file.

Since Core data creates three files for database, which are:

• db.sqlite
• db.sqlite-wal
• db.sqlite-shm

Is core data able to replace "db.sqlite" with the new one, that is downloaded from server?
