Migration from GCM to FCM needed?

Question

Google just announced that Google Cloud Messaging is now Firebase Cloud Messaging. What does this mean for existing users of GCM and what migration (if any) are needed?

Answer 1

Firebase Cloud Messaging (FCM) is the new version of GCM. It inherits the reliable and scalable GCM infrastructure, plus new features! See the FAQ to learn more. If you are integrating messaging in a new app, start with FCM. GCM users are strongly recommended to upgrade to FCM, in order to benefit from new FCM features today and in the future.

1. FCM is the new version of GCM under the Firebase brand. It inherits GCM’s core infrastructure to make sure we continue to deliver messages reliably on Android, iOS and Chrome.

2. Yes some features of GCM is deprecated, but they are supporting all previous clients.

3. To upgrade from GCM SDKs to FCM SDKs, please see the guides for migrating Android
