[OpenIndiana-discuss] How to install a different OS version from scratch, NOT as an upgrade, in a separate BE (or however one might do it) on an OSol B134 machine

[Hans J. Albertsson]

I have an installation of OpenSolaris b134, with lots of addons: SunRay 
Software, mplayer, VirtualBox... almost anything I could find got installed.
Make no mistake: it is ALL useful to me and my users, so there isn't 
anything that can be removed out-of-hand.

But: We do want to move on! OI b148 is my target, right now.

I have tried to upgrade from OSol b134 to OI b147 or b148 since OI 
became available. I have tried everything and it's aunts, to NO avail.

Is there a way to install a separate OI b148 from scratch? Like 
installing from the bootable DVD iso, on the same machine, w/o 
interfering with the existing OSol b134 environment.
Is there a way to create an empty Boot Environment and install onto 
that? Or can one do it in some other, involved way?



Note:
In the last few months, I have received massive amounts of "advice" on 
upgrading b134->b148, but none of the advice has been in any way useful.

SO:

I have given up on the upgrade path, at least unless someone can 
actually provide some insight and/or sources of knowledge on how the 
upgrade works, what could trip it up and what one can do to push past 
any problems.
