I thought lenny→squeeze was the most complicated, because lenny's standard kernel was not compatible with the upgrade process and had to be upgraded in a preliminary step. That could then lead to knock-on effects with non-free firmware. And, for safety, udev had to be immediately upgraded because of the new kernel, then the system rebooted to bring them into operation before the upgrade. > I'm not that bothered about downtime (within reason, the > Debian lists get very stroppy when their emails bounce) but some people > are.

How about getting those freeloading critics to fork out for a new drive so that you can build and test a second system (dual-bootable) during your scheduled downtimes. > What is more worrying is having to wing it through a procedure > which has not been tested fully and described in the upgrade documents, > but it does appear that will not be the case here.
