Uh -- why upgrade to a branch (5.x) that has already had it's last release and is worse performing than both 4.x and 6.x? You should really be looking at upgrading to 6.2-RELEASE just as soon as it comes out (Real Soon Now). As for risk -- for various reasons you will be better off doing a clean install of 6.x and rebuilding your server from the ground up. It's no more risky than installing any other server -- unless you have some legacy binary-only application that you absolutely have to run, it is virtually certain to succeed. You biggest problem would seem to be the downtime required to do the update -- if you can manage it, probably the least consumer impact method is building the upgraded system on fresh disks on a scratch box, and then finishing the upgrade by a disk-swap. Which also has the added benefit that you have a ready-made back out path.
