Q. How can I move a secondary Systems Management Server (SMS)/ Microsoft System Center Configuration Manager (SCCM) site to a new primary site?

A. You cannot move a secondary site to a new parent; you can only uninstall, then reinstall the secondary sites. If you do not delete the SMSPKG and SMSPKGx$ folders, you can use the preloadpkgonsite.exe tool that is part of the SMS toolkit to avoid having to resend packages down the network for SMS sites. SCCM has the population capability built-in for packages
