Migrating data out of firestore is a bit tedious, but not difficult. It just requires a lot of iteration. That said, if I were simply looking for realtime updates for a subset of my data (and was determined to use the firebase system) I would go for realtimedb over firestore every time. It's much simpler, cheaper, and export, when necessary, is straightforward.
