Hi Gordon,

actually, upgrade with ZFS support will be addressed by Snap Upgrade 
project.
For details, please take a look at

http://opensolaris.org/os/project/caiman/Snap_Upgrade/

Since I am not sure, if there is some reasonable way to hack exiting 
pfinstall
engine for this, I am CCing Lori Alt, who is ZFS expert and her team 
originally
delivered initial support for pfinstall being able to install on ZFS 
root. I am not
sure, if any research was done as well as pfinstall upgrade is concerned.

Best regards,
Jan
