SQL 2012 Upgrading using your SA

When you upgrade from SQL Server 2008 R2 (or below) to SQL Server 2012 using your Software Assurance rights you can continue to use your existing license model until the end of your Software Assurance cycle. This means that if you have CPU licenses under SQL Server 2008 R2 you can continue to use those CPU licenses under SQL Server 2012 until your Software Assurance expires. Once it expires you will need to true up on the number of CPU Cores.
