Migration Guide

Why is Migration required?

Changed Implementation

1. Push Notifications extension was initially implemented using TOPICS.
2. The Enhanced Push Notification uses the Token-based approach which simplifies the overall process of implementation for a developer and does most of the heavy lifting for you.
3. This transition involves changes in the front-end code of your app.
4. Most of the complex code of registering and unregistering to topics has been removed and replaced with one method to register the FCM Token with the extension.

Your app's user base

1. You may release a new app having the Enhanced Push Notifications implementation. But your user base won't update the app at the same time.
2. In such a scenario, we give you the flexibility to use both versions of Push Notifications at the same time until all your users are on the latest version of your app.
3. Once you are confident that all the users of your app are on the latest version, you can use just the token-based push notifications

How to migrate?
