I have s SBS 2011 as the DC with 50 CALs. I want to add windows 2012 standard server and install SQL 2012 on it. I know that I will need a windows server 2012 license and SQL license (with CALs or core-based) but do I also need separate CALs for windows 2012 or is that covered with the SBS Cals. I believe if I add a windows 2008 server then separate CALs are not needed. Thanks.
