Microsoft SQL 2012 RTM’d yesterday (link) and you’re probably wondering: “Can I upgrade my SQL Server instance to SQL 2012 if it hosts CRM databases?” and the answer is YES!  For CRM 2011 make sure you’ve installed update rollup 6 and for CRM 4.0 you should install update rollup 21 before upgrading.  After the upgrading to SQL Reporting Services 2012 remember to install or re-install the Report Connector (details in the KB below).  More details are available from the resources below:
