Hi Jerry and Ramesh, With respect to 6246943 there are no plans to make the current flash tools zone aware. As for upgrading from s10u3 to s10u5 I don't know of any reasons why the same procedures used for u3 wouldn't work for u5. Just in case I'm forwarding this on to the install-discuss alias to see if anyone else has any thoughts on possible issues. For more information on what is being done for future releases see http://opensolaris.org/os/project/caiman/ Thanks, -evan
