Checklist: Upgrading Your Azure Deployment
Throughout the rolling upgrade process, services not actively being upgraded would continue to be available. Services that utilize the ArcSight Database, such as event ingestion and search, would be interrupted during the Database upgrade phase, but any in-flight data would be cached and processed as soon as the Database upgrade completes.
If you deployed and configured your system for high availability, during the rolling Kubernetes worker node upgrade process, services delivered by pods on the affected worker node would be restarted on another worker node. Similarly, the upgrade of Kubernetes pods is performed in a rolling manner, so there would be a brief pod-level service pause as pods are restarted to perform the upgrade. Some services, such as Transformation Hub, can be configured for high availability with pod replicas so that there are no service pauses during the rolling upgrade.
Use this checklist to complete the upgrade tasks in the listed order.
