zfs discuss - Dec 2009 - Live Upgrade Solaris 10 UFS to ZFS boot pre-requisites?

I have a Solaris 10 U5 system massively patched so that it supports 
ZFS pool version 15 (similar to U8, kernel Generic_141445-09), live 
upgrade components have been updated to Solaris 10 U8 versions from 
the DVD, and GRUB has been updated to support redundant menus across 
the UFS boot environments.

I have studied the Solaris 10 Live Upgrade manual (821-0438) and am 
unable to find any statement which requires/suggests that I live 
upgrade to U8 with UFS boot before live upgrading to ZFS boot but the 
page at http://docs.sun.com/app/docs/doc/819-5461/ggpdm?a=view 
recommends that this process should be used.  The two documents do not 
seem to agree.

Given that my system is essentially equivalent to U8, is there any 
reason to live upgrade to UFS U8 prior to ZFS U8 or can the more 
direct path be used?

Hi
the live upgrade info doc
http://sunsolve.sun.com/search/document.do?assetkey=1-61-206844-1
has all the relevant patch, if you are on u6 KU or higher ( you are on 
u8 ), then you can just migrate straight to zfs, so there is no need to 
upgrade to u8 ufs, in order to move to u8 zfs, the u6 KU delivers the 
sparc new boot for zfs boot etc, jsut make sure you take the very latest 
live upgrade patch 121430-43
