• For SBS 2011 to 2012 R2 migration without Exchange, brief steps here:
  1. Install Server 2012 on the new server, join to the domain. ( Upgrade the schema etc... on the old server with 2012 DVD)
  2. Promote it to a domain controller, make it a global catalog server and a DNS Server.
  3. Wait for everything to replicate, then move your data if needed.
  4. Install DHCP on the new server (same scope as the SBS 2011), then shut down DHCP services on the SBS server and activate on the new server.
  5. Transfer the FSMO roles.
  6. DC Promo the SBS server out of the domain.
  7. Shut down the SBS server.

  These steps are applicable for transition from all the versions of Small Business Server to Windows Server 2008/ 2008 R2/ 2012.
