Hi Team,
    I can't find any documentation or guidance on the expectation of the
downgrade of stateful Kafka stream application (which has different rocksdb
versions embedded).
    For example, if we upgrade from 2.2 to 2.5 (with binary upgrade only
and using the same eager protocol) and somehow found some problem and
downgrade to 2.2. What is the expectation?

Thanks!
Ming
