Absolutely right about upgrades!!

I used flars to "upgrade" our Solaris 8 Sun Ray/ Citrix servers to Solaris 10 (i.e. I took a snapshot of one of the Solaris 8 systems, used that build a new system (with all of our stuff), upgraded the new system, and then used a flar of that to build the Solaris 10 systems. Even with tons of self-compiled code, including GCC, KDE 3.x, etc. I ran into very few problems. I do not recall having to make too many changes. I think I created the Solaris 10 flar I used was the second or third one I had created (mostly tweaking stuff).

Of course, I did not take the "upgrade" for granted. I used the flars, set up a pilot Sun Ray/Citrix server that a few of used for a couple weeks to detect issues, etc. And because of that, the problems that we did encounter (nothing too major) were resolved before I rebuilt the new systems.

Of course, to our users, it was a fairly smooth transition, all things considered. But they didn't see the months of effort that went into making sure things went well. Anyone that assumes an upgrade will go well, especially for a production system, deserves to get fired when -- shock of all shocks -- the upgrade doesn't go as well as expected. Don't take your upgrades (or your SysAdmins) for granted!! (^_^)
