Upgrading the Experience Manager

The Experience Manager user interface for in-context editing replaces SiteEdit if you are upgrading from an SDL Tridion instance with SiteEdit added. If you are upgrading from SDL Tridion 2011 SP1 with the new user interface installed, running the installer updates the user interface. Note that to upgrade Experience Manager, you also need to upgrade the Content Delivery Server Roles (Web service and Web site extension) associated with Experience Manager (called Session Preview previously).
