You cannot use the kafka-topics tool to move replicas to other brokers. To learn how to move replicas, please see the "Custom partition assignment and migration" section here<http://kafka.apache.org/081/documentation.html#basic_ops_cluster_expansion> .
Hope that helps! If not, please let us know, we are interested in improving the quality of our documentation.
