Hi Tommy,
I think it's reasonable to think it should work. However, our upgrade tests
don't currently test that scenario and that is why we only mention
{0.8.2.x, 0.9.0.x} to 0.10.0.0:
https://github.com/apache/kafka/blob/trunk/tests/kafkatest/tests/upgrade_test.py#L62
The best way to verify would be to update the system tests to include older
versions that are expected to work and, if they pass, update the upgrade
documentation. I suggest filing a JIRA. Contributions are also welcome!
