+ <li>Brokers that are in <b>ZK mode</b> store their metadata in Apache

<li>Brokers that are in <b>KRaft mode</b> store their metadata in a KRaft
quorum. This is the new and improved mode of handling metadata.</li>
<li><b>Migration</b> is the process of moving cluster metadata from
ZooKeeper into a KRaft quorum.</li>
</ul>
<h3>Migration Phases</h3>
In general, the migration process passes through several phases.

+ For
<ul>
- <li>In the <b>initial phase</b>, all the brokers are in ZK mode, and there
is a ZK-based controller.</li>
- <li>During the <b>initial metadata load</b>, a KRaft quorum loads the
metadata from ZooKeeper,</li>
- <li>In <b>hybrid phase</b>, some brokers are in ZK mode, but there is a
KRaft controller.</li>
- <li>In <b>dual-write phase</b>, all brokers are KRaft, but the KRaft
controller is continuing to write to ZK.</li>
- <li>When the migration has been <b>finalized</b>, we no longer write
metadata to ZooKeeper.</li>
+ <li>In the <b>pre-migration phase</b>, all the brokers are in ZK mode, and
there is a ZK-based controller. But a KRaft controller has been provisioned and
has migration enabled</li>
