The information in this topic applies only to System Center 2012 Configuration Manager SP1.

With System Center 2012 Configuration Manager SP1, you can expand an existing stand-alone primary site into a hierarchy with a central administration site.

Before you run Setup to expand a stand-alone primary site, review the following sections in the Planning for Sites and Hierarchies in Configuration Manager topic:

Expand a Stand-Alone Primary Site

To expand your stand-alone primary site, run Setup from the Configuration Manager SP1 source media, and use the procedure To install a central administration site from the Install a Central Administration Site section in the Install Sites and Create a Hierarchy for Configuration Manager topic. During Setup, ensure that you make the following selections in the Configuration Manager Setup Wizard:

  1. On the Getting Started page, select Install a Configuration Manager central administration site.

  2. On the Client Language Selection page, select the same client languages that the primary site supports.

  3. On the Central Administration Site Installation page, select the option Expand an existing stand-alone primary site into a hierarchy.

After Setup finishes, your stand-alone primary site is now a child primary site. After the new central administration site is installed, restart any Configuration Manager consoles that are open and remain connected to the primary site. If there are software update points at the primary site, install a software update point at the central administration site and configure it to synchronize software updates with Windows Server Update Services (WSUS). This is because the child primary automatically reconfigures its software update points to synchronize with a software update point at the central administration site. For information about how to configure software update points, see Configuring Software Updates in Configuration Manager.
