In this section, we consider two upgrade scenarios. The first scenario assumes that two separate Hybrid Data Pipeline clusters have been deployed: a test environment and a production environment. In this scenario, we recommend an upgrade of the test environment, followed by an upgrade of the production environment. The second scenario does not presume the existence of a test environment. In this case, we recommend creating a clone of the cluster, upgrading the clone, and then updating the DNS record for the load balancer.
