As of compile firebase-database:11.0.1, this is the same function with the new class references (https://firebase.google.com/support/guides/firebase-android July 05 2017)

private void moveGameRoom(final DatabaseReference fromPath, final DatabaseReference toPath) {
        fromPath.addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                toPath.setValue(dataSnapshot.getValue(), new DatabaseReference.CompletionListener() {
                    @Override
                    public void onComplete(DatabaseError firebaseError, DatabaseReference firebase) {
                        if (firebaseError != null) {
                            System.out.println("Copy failed");
                        } else {
                            System.out.println("Success");

                        }
                    }
                });

            }

            @Override
            public void onCancelled(DatabaseError databaseError) {

            }
        });
    }
