You would need to upgrade your Kafka Server first if you have not done so.
After that you can first follow this as you mentioned:
to move the committing offsets from ZK to Kafka (note there is a phase
where you will do double committing to read offsets from ZK while writing
to Kafka). Then you can upgrade to the new consumer.
