I'm working on this right now.
Basically the idea is to stash away build and data dirs (after we've run
regression, PL and contrib testing) for stable branches (via a command
line option) and then test upgrading them. A trial run on the first part
is currently running. Once I have that sorted out I'll work on the
testing bit ;-)
