The general concensus was that this is not supported, but may be a feature
in Solaris 8. A couple of people suggested doing an install on
an identical machine then moving the disk across, but I havent
got a spare machine of the same architecture :-(
Cyril Godon says he managed to a similar thing moving from 2.3 to 2.5.1
- I've included his email below. Unfortunately I havent got the time
or the nerve to experiment with this on my big shiny server!

I did it from 2.3 to 2.5.1 some years ago (I had to upgrade 150 remote
solaris servers, and it was the only way I found to do it fastly).
I don't remember all the steps but the main command is pfinstall.
You must give it a jumpstart profile.
If you configure properly the environment before you call it, it was (in
2.3) able to install a 2.5.1 solaris image while solaris 2.3 was running.
You should look at the startup scripts and commands from the cdrom to
identify all the steps needed.
I remember the only problem encountered was something about swap. 2.5.1
pfinstall removed the swap slices before adding the new ones. It was why I
used the 2.3 pfinstall instead.
Building such an install procedure is very long since there is no
documentation about the different install commands and scripts...
This is also not a very supported way to install solaris.
I hope this will help you and I would be very interested in knowing the
results of your tests (if any),
