OS upgrade in Suse Enterprise Linux Micro Systems

Hi Folks,
I would like to get inputs how should we plan for upgrade of OS (or) updates to the Suse Enterprise Linux Micro (SLE-Micro) ? What’s the link to be referred and where can i find the procedure.
Now, I have SLE-M 5.2 running, and needs to be prepared for automated upgrade for these systems.

Thanks for insights

Team, Could you please share some lights on this… atleast basic command line options to do the upgrade from SLE M 5.1 to 5.2 etc, like service pack ugprade (or) critical patches etc
