> Our docs, and code, both explicitly say that you should drain a node before upgrading to a new major release.
> If you don't do what the docs explicitly tell you to do, however, Cassandra won't scream at you. Also, we *do* currently have logic to replay 1.2 commitlog in 2.0, but it seems to be slightly broken, unfortunately.
