Cannot set kraft.version to 1 unless one of the flags --standalone, --initial-controllers, or --no-initial-controllers is used. For dynamic controllers support, try using one of --standalone, --initial-controllers, or --no-initial-controllers.

Note: Currently it is <b>not</b> possible to convert clusters using a static controller quorum to
use a dynamic controller quorum. This function will be supported in the future release.
Note: To migrate from static voter set to dynamic voter set, please refer to the <a href="#kraft_upgrade">Upgrade</a> section.

<h5 class="anchor-heading"><a id="kraft_reconfig_add" class="anchor-link"></a><a href="#kraft_reconfig_add">Add New Controller</a></h5>
If a dynamic controller cluster already exists, it can be expanded by first provisioning a new controller using the <a href="#kraft_nodes_observers">kafka-storage.sh tool</a> and starting the controller.
