Shutdown the old API Gateway instance
If migration is successful and the new API Gateway nodes are stable, shutdown the old nodes so that they do not send any metrics to any configured destinations like API Portal, external Elasticsearch, and so on. The new instance now receives the runtime transactions. You can remove the old instance's endpoints from the load balancer.
