How to Add a Site
The Commerce Sites container, as it appears in Commerce Server Manager, is created when you install Commerce Server 2009 R2. When you unpack a site, site instances are created from a package for each site and appear as subfolders in the container. You add sites and site resources by using Commerce Server Manager and Commerce Server Site Packager.
You add a site to Commerce Server 2009 R2 by using Commerce Server Site Packager to unpack a site. For instructions, see How to Unpack a Site.
