Hi Vigan Vula,
Thank you for your patience while we are reviewing your issue.
Based upon your query, To shut down telemetry, could you please try below troubleshooting steps
1.Check the configuration settings in the Azure portal for the classic Cloud Service and ensure all endpoints and monitoring settings are disabled. If you can't shut it down directly, consider stopping the service or removing any dependencies still sending data.
2.To redirect traffic to the upgraded service, update DNS records to point to the new Cloud Service (Extended Support). Ensure that all application configurations, connection strings, and environment variables are updated to the new service endpoint. Additionally, use Azure Traffic Manager or a load balancer to manage traffic effectively, and communicate with users to make sure they are aware of the new endpoint.
