Hi there, I'm currently developing an app that use redux persist (using asyncstorage) to store UI state and SQlite for user specific data. Now I am trying to add synching feature to allow my premium users to get their UI settings and data synced seamlessly and thinking to accomplish that with firebase (since apparently it's the stack to go when we dont have enough resource to handle the backend)

My question is, is it a good idea to have this "dualism" in an app? (regular user will use asyncstorage and SQlite while premium will be connected to Firebase Realtime Database). Or should i ditch asyncstorage and SQlite and just use firebase for all users?

Also if there's anyone who has experience in database sync, it will be so helpful if you could give me directions. Thank you
