<ol>
<li>Upgrade the brokers one at a time: shut down the broker, update the code, and restart it. Once you have done so, the
brokers will be running the latest version and you can verify that the cluster's behavior and performance meets expectations.
</li>
<li>Once the cluster's behavior and performance has been verified, bump the metadata.version by running
<code>
./bin/kafka-features.sh upgrade --metadata 3.4
</code>
</li>
<li>Note that the cluster metadata version cannot be downgraded to a pre-production 3.0.x, 3.1.x, or 3.2.x version once it has been upgraded.
However, it is possible to downgrade to production versions such as 3.3-IV0, 3.3-IV1, etc.</li>
