If you are running the same version of Cassandra in both cases, you are
probably fine. As you point out, one must inevitably upgrade one's OS; I
recently went from ubuntu 1004 to 1204 (with associated (1.6/1.7) JVMs)
without any problems.

But you should of course do any such activity in QA and staging and let it
burn in for a while before doing so in prod.
