I currently have a Druid cluster running version 0.17 and I’m planning to upgrade it to version 0.22.1. I am looking for guidance on the best practices and steps to follow for this upgrade.
What are the key steps involved in upgrading a Druid cluster from 0.17 to 0.22.1?
Are there any critical configuration changes or migrations that I need to be aware of?
Should I consider upgrading Kafka or any other dependencies as part of this process? If so, what versions are recommended?
How can I ensure a smooth and minimally disruptive upgrade process for my production environment?
Are there any known issues or pitfalls with this upgrade that I should watch out for?

I currently have a Druid cluster running version 0.17 and I’m planning to upgrade it to version 0.22.1. I’ve already set up two versions of the Druid cluster, but I’m unsure about the next steps.
