Assuming the partitions are replicated, a migration plan could be: - install latest kafka on broker $i, /etc/kakfa-NEW - update server config in /etc/kakfa-NEW/config/server.properties to match the old one (in particular zookeeper.connect and log.dirs) - stop broker $i - start broker $i from /etc/kakfa-NEW/bin/....
I successfully did that for a 6-broker cluster going from 0.8.1 to 0.8.1.1.
