Or upgraded from a SAN device. In our setup, we have a image copy of
the VMS 8.4 CD distrubution on an SAN volume that is bootable. We
can shutdown a system, boot from the VMS 8.4 dist SAN device and
then just run the upgrade "as usual". And you can select "INSTALL"
or "UPGRADE".

Yes, I had to use the detailed commands, quickset was missing something.
Here is a copy of the command that I saved:
