Kafka allows increasing the replication factor of a topic. You can read about it here <http://kafka.apache.org/081/documentation.html#basic_ops_increase_replication_factor>. We do not support reducing the number of partitions, so you either have to create a new topic or delete the existing one. We fixed a number of bugs in delete topic but those fixes are on trunk. You can give it a spin.
