> As per [~mjsax] comment [here|https://github.com/apache/kafka/pull/10747#pullrequestreview-1376539752], we should add a system test to test the rolling upgrade path for [KIP-904|https://cwiki.apache.org/confluence/x/P5VbDg] which introduces a new serialization format for groupBy internal repartition topics and was implemented as part of https://issues.apache.org/jira/browse/KAFKA-12446 
> There is `StreamsUpgradeTest.java` and `streams_upgrade_test.py` (cf `test_rolling_upgrade_with_2_bounces`) as a starting point.
> Might be best to do a similar thing as for FK-joins, and add a new test variation. 
> The tricky thing about the test would be, to ensure that the repartition topic is not empty when we do the bounce, so the test should be setup accordingly.
