Upgrading an AKS Cluster

You have the choice to automatically upgrade your AKS clusters or to manually manage upgrades yourself. As part of your upgrade decisions, you can decide whether you would like to upgrade both the node pools and control plane or the control plane only. Automatic upgrades provide different channels that best apply to your requirements; these are listed as follows:

• None: Used for disabling auto upgrading
• Patch: Used to update the cluster automatically to the latest support patch version
• Stable: Used to update the cluster automatically to the latest stable version
• Rapid: Used to update the cluster automatically to the latest N-2 minor version
• Node-image: Used to update the cluster automatically to the latest version available

Note

When upgrading your AKS clusters, you will upgrade to a supported patch version for your cluster, one version at a time where more than one version upgrade exists.
