> Since 0.8 is a non-backward compatible release, we need a migration tool. One way to do that is to have a tool that can mirror data from an 0.7 Kafka cluster into an 0.8 Kafka cluster. Once the mirror is set up, we can then first migrate the consumers to the 0.8 cluster, followed by the producers. After that, we can decommission the 0.7 cluster.
