Integrating both Firebase Cloud Messaging (FCM) and Google Cloud Messaging (GCM) on the same App

[Redan Hassoun]

Hi ,
I am quite new in implementing mobile push notifications , i have an android application (which is connected to a PHP application server) and uses GCM for delivering push notifications , in the application database they
defined the GCM token as the unique identifier for each user in the application ( I know it's a bad idea ).
I am asked to switch to the Firebase cloud service in order to receive push notifications.

The problem is : If i just migrate from GCM to FCM , the existing users of the application will lose access to their accounts , because the GCM token will be gone.

I think the only walk-around is to run both of the services on the application..

Is this possible ?

If it`s not , do i have another solution ?
