So I am also nervous. My first failure was with a-kind-of hardware raid, ar, built with cheap VIA VT6421A controller. After installkernel the system refused to boot and on its display was message "hardware failure, you have to destroy and build the mirror again. You will lose ALL data". Frightening, isn't it. So i tested the disks, found them OK and replaced the controller - newer MB with GEOM mirror. Reformat, of course, occurred and all the data was salvaged from the mirror disk. Now I see the card works. It's something with FreeBSD 8.0. This system was installed with FreeBSD 5.1 about may be 4 years ago and upgraded via cvsup til now. I'm sharing this experience to bring your attention to major advice in the update procedure - to take full backup. I think good RAIDs do not store data on the disks in readable by any adapter with same interface format. My question is: how can I guess the result - "Glory" or "Sorrow" BEFORE starting the update? Otherwise, needless to say, 8.0 works perfectly. I mostly use AMD64 version.
