Migration to System Center 2012 Configuration Manager
From the archive (2012). Written for the tools of the time, so some details may be out of date.
Eric Orman, a Program Manager for System Center Configuration Manager put up a nice post covering some common questions for the migration of Distribution Points to ConfigMgr 2012.
My favorite migration feature within System Center 2012 Configuration Manager is Migration Distribution Point upgrade, which is the ability to perform an in-place upgrade of an existing Configuration Manager 2007 Distribution Point to a Configuration Manager 2012 Distribution Point, while also preserving migrated content and converting it into the new content library. The entire end-to-end process is orchestrated by creating a Migration Distribution Point upgrade job.
