How to sync already existing data in realm db

I have a situation in which I have an offline db with large data stored .

I want this data be synced with my server realm .

In this case I would have to copy the data from offline db and I would need to paste em into new db with "SyncConfiguration" config ?

or by any means I can sync the realm db which was created with "RealmConfiguration" . This way I can avoid data migration .

Solution

Currently, there is no way to sync a Realm that was originally created as standalone. You'll need to copy the data manually.
