<p>We have the version 1.12.10-gke.22 of kubernetes master, but we needed change to a 1.15.9-gke.24. </p>

<p>We running the command to clusters upgrade : </p>

<pre><code>gcloud container clusters upgrade  &lt;cluster-name&gt; --master --cluster-version 1.15.9-gke.24 --zone us-central1-c
</code></pre>

<p>And we receive the response: </p>

<pre><code>Master cannot be upgraded to "1.15.9-gke.24": cannot upgrade the master more than a minor version at a time.
</code></pre>

<p>In Google Cloud Platform console, we have the message: </p>

<p>Some of our customers experienced the same error. They cannot upgrade from 1.12.10-gke.22 because the 1.13 upgrade is not available. </p>

<p>The fix is in the works currently. Meanwhile to workaround the issue you can create a cluster with master version 1.15.9-gke.24 and migrate your workloads from the old cluster.</p>
