I don't believe there should be any changes that will have a noticable
impact on the users.  Messages version 7.X was primarily a code cleanup
-- the version is more internally consistent, and (I believe) less buggy
than 6.23, which appears to be what you're running now.  Also, there are
a few really neat new features...  At any rate, I don't think there were
any changes to the user data file formats.  

Obviously there's always a chance that you could compile things with
some options wrong, so you do want to test it out a bit before releasing
it to your users.  The problems you're likely to have are not related so
much to data formats as to things like whether the resolver is running,
etc.  

When you make the upgrade, be sure to get the patches that have been
released -- things will run without them but you could spare yourself a
few bugs.

I also recommend upgrading your X11 release to R4; the performance
improvements are pretty amazing.  

Hope this helps.  -- Nathaniel
