Hmmmm, wouldn't I have to run upgradesstables BEFORE I start the 1.2.2 node? But running upgradesstables as I recall required cassandra to be running.....so does it somehow understand the old format when it starts I suspect?
I am thinking I just keep the node out of the ring while I run the upgradesstables, correct? But of course am not sure how to start a 1.2.2 node such that it does not join the cluster.
