These instructions will describe the migration of settings and data from an existing Small Business Server (SBS) 2003 or Small Business Server 2008 Standard domain to Small Business Server 2011. Furthermore, how the existing SBS server can be removed from the SBS 2011 network after migration will also be described.


  • Source Server: An existing SBS 2003/2008 Server, from which the settings and data will be migrated.

  • Primary Server: The first server in the SBS 2011 Standard Network, which contains more than one server.
  • Second Server: The second server in the SBS 2011 Standard Network. The Windows SBS 2011 Premium Add-on can be installed on the second server.
