<p>I began to try Google Container Engine recently. I would you like to upgrade the Kubernetes Cluster to the latest version available, if possible without downtime. Is there any way to do this?</p>

<p>Unfortunately, the best answer we currently have is to create a new cluster and move your resources over, then delete the old one.</p>

<p>We are very actively working on making cluster upgrades reliable (both <a href="https://github.com/GoogleCloudPlatform/kubernetes/issues/6079" rel="noreferrer">nodes</a> and the <a href="https://github.com/GoogleCloudPlatform/kubernetes/issues/6075" rel="noreferrer">master</a>), but upgrades are unlikely to work for the majority of currently existing clusters.</p>
