I am working on migrating my application from Realm Cloud to MongoDB Realm, as Realm Cloud will
close before the end of the year and I have a few questions about it:
During the migration, I will copy all the data from Realm Cloud to MongoDb, but how to be sure all users have synced their data to Realm Cloud ? If a user was offline last timed he used my application, data will not have been transferred to the Cloud and therefore they will not be on the new MongoDB server. Is there a way to know if all the data have been uploaded to Realm Cloud before performing the migration?
With Realm Cloud, local data is stored in a * .realm file. But what about MongoDB Realm ? Will it replace/delete the .realm file or will it create a new file ? If the .realm file still exists, I plan to transfer it on a storage server in case offline data was not synchronized during the migration, so I could always get them back.
MongoDB Realm sync is still in beta, when will it no longer be ? When Realm Cloud will be closed, will it work ? Do I have to wait before migrating? Because sync is essential for my app.
Thanking you for your help.
