Patching Procedure in Solaris 10 with sun cluster having Solaris zone

Hi Gurus

I am not able to find the patching procedure for solaris 10 ( sol10 u11) to latest patchset with sun cluster having failover zones so that same I should follow.

Take an instance, there are sol1 and sol2 nodes and having two failover zones like sozone1-rg and sozone2-rg and currently both are present on sol1 node.
Both global zones are having ZFS root pool and we need to follow Solaris liveupgrade

Now kindly let me know step by step procedure

Note: After Global zone upgrade I need to upgrade failover zones as well.

If it is an important system, better hire a professional to do that job. It is a quite long procedure and there are to many variables to explain it in here...
