I'm trying to find out if you can run Server 2012 and SBS 2011 within the same domain. Now the 2012 doesn't include Sharepoint I would like to keep the SBS 2011 in place for the sharepoint functionality, but I would also like to start migrating the domain towards 2012. I would like to run 2012 as my primary DC and SBS 2011 as by secondary DC, but I can't find much information about the compatibility between the two.
