 Unfortunately, after I did so, neither was accessible in the original ring anymore.  I saw
the warning message in the logs about the token being reassigned.  Maybe I didn't give it
enough time, but accessibility faltered, so I reverted the IPs of the nodes, decommissioned
them each, swapped their IPs again, then brought them back into the ring one at a time.  That
seemed to work.  I admit that I'm still quite a novice when it comes to cassandra's workings,
and since my system was unresponsive for a time, my goal was bringing it back up, and I didn't
dive into extensive analysis.
