You can, but only via a manual procedure: http://dev.mysql.com/doc/mysql-cluster-manager/1.0/en/mcm-install-cluster-migrating.html. Note that this does involve downtime of the cluster when all nodes are restarted in order to use the new configuration files defined for cluster management. The procedure is provided on an “as-is” basis and it is the responsibility of the user to optimize it to their needs and then validate that it works before attempting to apply it to their live database.
