Thanks for taking the time to share this warning and your experiences!  I'm
familiar with the the limitation of hopping no further than 2 releases at a
time due to the DB schema changes and should have mentioned my awareness of
that in my original e-mail to not give good Samaritans like you panic
attacks.  So sorry for that omission on my part!

Past upgrades have been eventful.  I orchestrated our upgrade from SLURM 14
to 15 in May of 2016, and a previous administrator did the upgrade from
some prior version to 14.  In my case, for some reason running `make
install` omitted installing 2 compiled libraries from the .lib/plugins/
directory to the filesystem.  There were also other idiosyncrasies that
would have added a lot more time and stress to the outage had I not tried
simulating the upgrade first.  It's possible that others on this list have
seamless upgrade experiences, but that's the baggage I now carry around.
