Hey Folks, I am looking for some advice for one of my production workloads got mail from aws for shutting down some services and force to use new services.

We detected AWS AppSync APIs in your account leveraging GraphQL real-time subscriptions sending traffic based on our v1 protocol (MQTT over WebSockets) in the past 12 months. This is our final reminder on December 30, 2021, MQTT over WebSockets will be disabled for all AppSync APIs in all regions in favor of pure WebSockets.

Our recommended best practice is to have your APIs taking advantage of the v2 protocol (pure WebSockets) released in November 2019. We ask that you to update to pure WebSockets by December 30, 2021 to avoid any impact to existing applications. The update is easy and should only take minutes. Simply upgrade your clients to the latest AppSync SDK or Amplify clients for JavaScript/iOS/Android. The pure WebSockets v2 engine is used by default with the latest versions. The Amplify DataStore, which is a multi-platform (iOS/Android/React Native/Web) on-device persistent storage engine that automatically synchronizes data between mobile/web apps and the cloud, also uses our pure WebSockets protocol by default.

Please suggest me from where i start. I found the code snippet of above services in our code (web, mobile and api’s) Great Thanks! for your precious time

sounds like all you have to do is upgrade the appsync sdk

Thanks @Garret Harp

Thanks Garret!
