Have you ever looked at the Sun package Live Upgrade ? I have used it to
upgarde a couple of our servers and it went very well with limited
disturbance to the systems.

2.6 to 8 upgrade, copy boot disk, device issues

Uh, no.

Both a boot -r or a boot with /reconfigure don't do anything useful
until after the root filesystem is mounted read-write. If the devices
are screwed up, that won't happen.

Boot -r can fix *some* devices, but not those associated with the root
disk. Those must be fixed externally before the boot will succeed.

Gee, if it were me I would upgrade the machine though jumpstart. you
can edit the profile and preserve partitions so you don't lose data.
There are so many differences between 2.6 and 2.8 that I wouldn't even
attempt coping from one to the other. Jumpstart would work a whole
lot faster. I usually set up the jumpstart and kick it off right
before I leave. When I come back in the next morning, everying is
done!
