---------------------------------------

[~anigam] [~singhashish] I am doing some work right now on rolling upgrade/compatibility using ducktape - do you mind if I assign this to myself?

> To test protocol changes, compatibility and upgrade process, we need a good way to test different versions of the product together and to test end-to-end upgrade process.
> For example, for 0.8.2 to 0.8.3 test we want to check:
> * Can we start a cluster with a mix of 0.8.2 and 0.8.3 brokers?
> * Can a cluster of 0.8.3 brokers bump the protocol level one broker at a time?
> * Can 0.8.2 clients run against a cluster of 0.8.3 brokers?
> There are probably more questions. But an automated framework that can test those and report results will be a good start.
