Could any of you folks out there tell me whether it will be safe for me to "rev up" to R4 on top of existing R3 user data files? Specifically, most of our users have pretty highly populated .MESSAGES directories that I'm sure they'd want to access after our rev change. Are there any gotchas I need to be aware of before I start the upgrade? If it's of further help, no one here is programming in Andrew; we're just using stock applications that come on the contrib tape. Thanks in advance; if this info is deemed uninteresting to the group why not email it directly to me. Brian Capouch Saint Joseph's College brianc@saintjoe.edu

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
