title: Migrating 0.9 Apache Kafka Cluster to Confluent Kafka
body: <p>I am currently planning out a upgrade/migration of our Apache Kafka cluster to a Confluent Kafka based one. Our current cluster is 0.9
   is 0.10.
  Is it possible to simply decommission a old broker and reintroduce the upgraded confluent broker with the same broker id in-place?</p>
  
  <p>I am aware of the protocol version settings which have already been set on both old and ew broker.</p>
  
  <p>Thanks</p>
