Thanks for that link, I am more worried about any "gotcha's" caused by
upgrading the client to 7.1.8 or 8.1.2 before the storage servers get
upgraded (and start using the new authentication).   What I had not
realized until I saw the chart is that the new clients are NOT backward
compatible with old storage servers (which doesn't really affect me since
we have those all at 7.1.7.2 now).
