I did 6.06 -> 8.04 -> 10.04, and it broke. Badly.

The one box I ran Debian on was somewhat unusual, and I lost SMP capability on the box upgrading the one time I did. The box is a DEC AlphaServer 2100 (Sable), and Sable SMP is hard to get these days; the last Debian kernel I know of that supported it was a 2.2 series kernel......
Looking more like I'm going to do at least one, and possibly more, SPARCs on Debian, I'll get a little more experience with it then. I'd rather do CentOS, and be consistent across servers in terms of administration....

Rollbacks would be good.
The smoothest upgrades of any I've ever done have been on EMC Clariion gear and its FLARE operating environment. But that's controlled hardware, and tightly controlled software, not a general purpose OS, so not directly comparable.
