## Updating Kubernetes version
The Kubernetes version of a cluster can be upgraded to any version available in the region or zone fo the GKE cluster. Upgrading the master Kubernetes version does not automatically upgrade worker nodes. Nodes can be upgraded independently.
>**Note**
>GKE has removed basic authentication in 1.19+. In order to upgrade a cluster to 1.19+, basic authentication must be disabled in the Google Cloud. Otherwise, an error will appear in Rancher when an upgrade to 1.19+ is attempted. You can follow the [Google documentation](https://cloud.google.com/kubernetes-engine/docs/how-to/api-server-authentication#disabling_authentication_with_a_static_password). After this, the Kubernetes version can be updated to 1.19+ via Rancher.
