One extenuating reason is that IBM is more likely to have tested the upgrade path for release N from release N-1 than release N-2. This is somewhat of a special case (5.4 being the last release before a major architecture level-set), but the changes to 6.2 made public so far are going to be doozies, and you don't need another annoying thing to worry about while you're learning that stuff. I think this is one case where I'd put up a 6.1 floor system and run the 5.4 production system in a guest. If you have Linux guests, they're pretty self contained, it's going to be fairly easy to move them to 1st level quickly, and your CMS users (if you have any) can do testing with both environments easily. Also, 6.2 isn't that far off, so you could stay current and move from 5.4 to 6.2 also in a guest, staying supported all the time.
