Live upgrade will work with Flash Archives, I do not know if it will
work with jumpstart off the top of my head. If you have a machine
running the same OS, you should be able to flash archive it, seperate
out the configurations you don't want, and then use it on the upgrade.
It's not really what you're asking for, but it IS another opption if
you want to use Live Upgrade, and it turns out jumpstart won't work.
