How to Migrate Your GCM Key to FCM?

As Google has deprecated the GCM Key and has moved to Firebase Cloud Messaging, you would need to migrate your GCM Key to FCM key for your subscribers to be reachable.

The GCM was deprecated by Google in April 2018 and will be removed as soon as April 11, 2019. Hence the migration is important not only for the subscriber reachability but for reliable, scalable GCM infrastructure and new features.

Here are the Steps you can follow to migrate your GCM Key to FCM-

Step 1 – Login to your firebase account using your registered email id or the one you used to create the GCM key.
