Migrating SCCM 2007 to SCCM 2012 – Part 4 migrations begins

This is the checklist/worksheet I am using for the migration.  I will update this as the install progresses.  This checklist came from http://technet.microsoft.com/library/gg682006


The Sp1 Pre-Req check for SCCM 2012 is buggy I got different results each time I ran it. I finally manually checked everything then started the install.   Migration of collections has started.   Working with a few clients on both sites now.
