Upgrade from a Solaris 9 SVM Root Mirror to Solaris 10 ZFS Root Mirror with < 10 Minutes of Downtime

Description: As sysadmins, many times the entire task laid out in front of us has no documentation. One of the biggest skill an admin can have is the ability to problem solve, breaking down a large task into smaller sub-tasks. Often times, you might be able to find documentation on some of those sub-tasks. A perfect example is upgrading a server from Solaris 9 with root in an SVM mirror to Solaris 10 with a ZFS mirror. Not only is this large task doable, but thanks to LiveUpgrade, it can be done with less than 10 minutes of downtime (3 reboots @ roughly 3 minutes each)!
