Can you do the following -

1. Start a mirror Kafka cluster with the new version on a separate
zookeeper namespace. Configure this to mirror data from the existing kafka
2. Move your consumers to pull data from the mirror
3. For each producer, one at a time, change the zookeeper namespace to
point to the mirror and restart the producer.
4. Once the producers have moved to mirror cluster, shutdown mirroring and
old cluster.
