| >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. |
