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 if you would like to upgrade both the node pools and control plane or the control plane only. Automatic upgrades have the option of choosing different channels that best apply to your requirements; these are listed as follows:
- None: Used for disabling auto upgrading.
- Patch: The cluster is automatically updated to the latest support patch version.
- Stable: The cluster is automatically updated to the latest stable version.
- Rapid: The cluster is automatically updated to the latest N-2 minor version.
- Node-image: The cluster is automatically updated to the latest version available.
Top Tip
It's important to note that 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.
