<p>I have Standard GKE cluster and want to migrate all my running services to new Autopilot cluster. I research official documentation and don't find anything how I can perform this migration</p>

<p>At the moment this operation is not possible to convert Standard GKE cluster to Autopilot GKE .</p>
<p>In GKE Documentation <a href="https://cloud.google.com/kubernetes-engine/docs/concepts/autopilot-overview" rel="noreferrer">Autopilot overview</a> under Other limitations you can find section <a href="https://cloud.google.com/kubernetes-engine/docs/concepts/autopilot-overview#no_conversion" rel="noreferrer">No conversion</a>:</p>
<blockquote>
<p>Converting Standard clusters to Autopilot mode and converting
Autopilot clusters to Standard mode is not supported.</p>
</blockquote>
<p>As stated by @guillaume blaquiere. You have to redeploy all your services. Backup and restore your data manually.</p>
