Update: Managed export and import are available .
There is currently no import / export service for Cloud Firestore. We are working on this, it is at the top of the list of what we need to do before we can discard the βBetaβ label.
You are correct that Firestore uses the same technology as Datastore, but the two databases do not match, so you cannot use regular export of data from Datastore.
At the moment, it is best to write your own import / export scripts using the Java, Go, Node.js or Python SDK.
