This is most likely not exactly what you are after, but:

Earlier in the week I put a message to -stable asking how to upgrade a 
minimal install of a system that runs entirely from USB key. This key 
was running 6.2.

Using a host build machine running 7.0, setting DESTDIR accordingly, and 
configuring numerous NO_* in /etc/make.conf, I was not only able to 
achieve my minimal install using buildworld etc process, I was able to 
upgrade it to stable sources from this morning successfully.

I'm now off to upgrade a box that is actually _running_ 6.2, and I'll 
report back with any details.
