Overview
upgrades consist of three parts:
- Upgrading the global cluster
- Upgrading workload clusters
- Upgrading Operators and Cluster Plugins
Users must upgrade the global cluster before upgrading any workload clusters.
Upgrading Operators and Cluster Plugins is optional. These can be upgraded during the cluster upgrade process, or separately after the cluster upgrade is complete.

Cluster Upgrade Feature
In the cluster details page, under Functional Components, the platform lists all components provided by the system. When a new version is available, the Upgrade button becomes active, allowing the user to perform the upgrade.
Notes
-
Kubernetes Version: Kubernetes upgrades are supported only for On-Premises Clusters. For Managed Clusters (e.g., Amazon EKS, Azure AKS), Kubernetes upgrades must be performed through the respective cloud provider. See Cluster Type for more information on the differences between On-Premises Clusters and Managed Clusters.
-
Operator: Only Operators with Source = are listed and can be upgraded via the cluster upgrade feature. All other Operators are managed through the OLM component in the Marketplace and are not included in this process.
-
Cluster Plugin: Platform-provided plugins can be upgraded through the cluster upgrade feature on both On-Premises and Managed Clusters, provided they are already installed.
-
DR (Disaster Recovery Environment): A DR environment contains both a primary global cluster and a standby global cluster, whereas a standard environment includes only one global cluster.
-
Primary global cluster: Defined as the global cluster that the access domain name resolves to.
-
Standby global cluster: Defined as the global cluster that the access domain name does not resolve to.
