I too read all the previous posts, but I still don't know what to do. Your mail
also indicates that your upgrade planning is based on several assumptions and I
think it is really time for IBM to jump in here. I think someone from
development should explain a little bit about the new security design and tell
us how we should upgrade without impact. Which components in which order to
which recommended level.
Kind regards,

Subject: Re: Should I upgrade to 7.1.8.x ??? (on the client end only)
Test! Test! Test! Search this forum for previous posts about this. There are a
bunch of gotchas. Perhaps one of the most severe is what happens to
administrator IDS. Create some dummy admin IDS to use in testing, because you
can permanently disable your own admin ID if you're not careful. We also know
there will be library sharing gotchas.
We're actually going to do the backup servers first - after thorough testing.
We think we can minimize the risk to things like admin IDS if we upgrade the
servers with NO clients yet on 7.1.8. I think that having 7.1.8 clients around
will greatly complicate the process of upgrading the servers, especially if any
of those 7.1.8 clients are the desktop workstations used by you and your
coworkers. It's possible that when you do eventually upgrade your servers to
7.1.8, you'll have to backtrack to each client and manually install new SSL
keys, on all client systems, all at once. I hope that cat-herding nightmare can
be avoided by upgrading servers first, which will then manage key distribution
among clients more gracefully, as they upgrade to 7.1.8 one at a time. If I'm
wrong about any of this, please chime in.
This thing has a big effect. Careful testing is necessary.

That said, v7.1.8 was a huge change so I would test it if possible first.
