I'd like to update to GCM 8.4 from 8.3, but part of the new process requires auto generation of a json file. I tried that with my existing project, but it created a new api key of type "Android" while the api key I was using before was of type "Server". Is it possible to use my existing "Server" key so that existing users continue getting push notifications? If so how am I supposed to go about doing so?
I can manually edit the json file, but I'm not sure how the old data I was using corresponds. The old information I have is the GCM_PROJECT_ID and a GCM_CLIENT_ID (same as project id except with some sort of hash and has "apps.googleusercontent.com").
Any help is appreciated.
