Firebase and Google Cloud projects consolidation

Question

I've opened a Google cloud project with multiple GCE, SQL and storage instances, along with an android app linked to it, about a year ago. In addition I've had 2 Firebase projects, one for production and one for dev environments, that were of course not linked to my Cloud project.

Now that the new Firebase is here, I would like to link all these accounts.
I have imported my Cloud project to the Firebase console, but it has its own Firebase DB, I'm not able to link it to my actual Firebase DBs (projects)... I can see my App analytics and cloud messaging but not my Firebase data, as the two Firebase projects are still considered as other projects.

How do I link or consolidate all these accounts together, Cloud and Firebases? And if not all, what about only the production one into my Cloud project?

This is how my Firebase dashboard looks right now:

Answer 1

You can import your firebase.com app into a new Firebase project and you can separately import your Google project into a Firebase project. However, we do not support merging these 2 imported projects.

If you want to use Firebase Auth or Firebase Invites in your Firebase project and if you have your OAuth Client registered with another Google project, you can add the OAuth client ID of your Google project into your Firebase project.

Answer 2

@Aralizer, you should be able to use Analytics, Crash reporting etc on the project you import from firebase.com. This Firebase project can co-exist with your previous Google Cloud project for GCE, Cloud SQL etc. It seems like you may have registered an OAuth Client in the Cloud project that you want to reuse in the Firebase project. This is possible by whitelisting the Cloud project's OAuth client ID in the Firebase project.
