Hi Martin, even though with Kafka I as a fellow user never found it problematic to just give upgrades a shot no matter the version increase in a test environment, since you are still on 0.8 you should thoroughly study the details at this link and depending on whether you care about one or more of them, or not, make a little plan on how to upgrade: https://kafka.apache.org/documentation/#upgrade
Good thing is this upgrading chapter covers all versions back to including 0.8 It has some tips here and there you may want to consider, e.g. upgrading broker first before upgrading clients.

At this moment we are running 3 Kafka (0.8) broker cluster. We want to try to upgrade our cluster to Kafka 1.0. Is there any recommendation for migrating from 0.8 ? Would it be possible to move directly from 0.8 to 1.0 or we should go through all the intermediate major releases ? Our client consumers and producers are ruby or jruby apps. Thanks before hand! Best, Martín
