Azure Kubernetes Service upgrade

Azure Kubernetes Service (AKS) cluster requires regular updates to the Kubernetes versions. Using the latest AKS version supported by Cloudera avoids compatibility issues between Cloudera Data Warehouse and Azure resources.

Using the Azure CLI or Azure portal to upgrade the AKS cluster is not supported. Cloudera Data Warehouse automatically provisions the latest supported AKS version when you activate an environment in Cloudera Data Warehouse. For more information on the AKS version, refer Version mapping for supported release.

To upgrade to the latest AKS, you must deactivate and reactivate your Cloudera Data Warehouse environment. To restore the state of your Cloudera Data Warehouse cluster after reactivation, Cloudera recommends using the backup-restore functionality. For more information, see Backing up and restoring Cloudera Data Warehouse.
