Can I subscribe a topic to another topic in Firebase Cloud Messaging

Is there a way to subscribe a existing topic to new topic in Firebase Cloud Messaging, so that all the registered clients of old topic will be registered to new topic.

Example: If I have a FCM topic name A and I create a new FCM topic B. Can I add topic A to topic B?

No, only client apps can determine which topics they want to subscribe to in order to receive messages. You can't route messages going to a topic through another topic. What you would have to do instead is program the server side code that sends the message to send to multiple topics as needed.
