During the upgrade to a System Center 2012 Configuration MANAGER Distribution point, all migrated content is copied and then converted to the single INSTANCE store. When you MIGRATE to a hierarchy that RUNS System Center 2012 Configuration Manager with no service pack, the original Configuration Manager 2007 content remains on the server until it is MANUALLY removed. However, when you migrate to a hierarchy that runs System Center 2012 Configuration Manager SP1, the original Configuration Manager 2007 content is removed after the copy of the content is converted.
