SQLite and iCloud do not mix well. Although it's possible to use the iCloud file APIs to put a SQLite file in iCloud, doing so is almost guaranteed to corrupt the file. SQLite wasn't designed with this kind of use in mind, and between external journal files, uncommitted transactions, etc, it's not even a question of whether the file gets corrupted, only of when (and the answer is "very soon").

Although Core Data can use both SQLite files and iCloud, it doesn't sync the SQLite file. Instead it has a scheme that uses transaction logs to send changes back and forth.

If you want to use your existing data with iCloud, you'll probably have to do something similar. I don't know of any good reference implementations. Basically, you'll need to export your data to some other format, and detect and import changes from other devices.
