My android app has not been updated for a couple of years and is still using a non-sync Realm V5.15.1. I would like to update it to the latest MongoDb version with sync capabilities for users. I also need to make changes to a lot of the classes and fields. What is the best way to update while making sure users retain their data?
I have been unable to find resources dealing with this scenario. Any advice, tips, links or guides will be greatly appreciated.
