Of course --- but do keep in mind that the reason for this was to
do a meanigful comparison;  SQLs being run and clicked on an
8.2.4 system vs. the same SQLs being run on a different hardware
with the exact same software.  If for some reason I conclude that
the 8.2 seems to offer better performance with the given hardware,
then of course I would go with the latest 8.2.x ...

If you're referring to the existing installation, well, yeah, I've been
meaning to upgrade it, but I guess now that we are going with a
hardware upgrade as well, then the software upgrade will be a
side-effect of the maneuver.
