How to upgrade new Firebase app from exist old app?

Question

How to update exit old app to new on

Answer 1

I've had a somewhat similar problem. I see the import button but when I click it, and select the project I want to load, it only displays the spinner. Ive even tried to import JSON from an old firebase project (before the upgrades) and it just spins. Could it be that the old JSON is not what the new firebase is expecting?

EDIT OK, seems it doesn't like Chrome. Works in IE 11 but not Chrome 50.0.2
