SQL Server with core-based licensing requires a minimum of four core licenses to function. In order to use these products, you will need to obtain enough copies to cover the cores in the processors you plan to use with SQL Server. The server/CAL licensing products offered by TechSoup provide a single server license for a physical, virtual, or cloud-based server. SQL Server with server/CAL licensing requires each user or device that accesses the licensed server to have a client access license (CAL). It is most appropriate for administrators who know the exact number of users and devices that will connect to the server.For more information on licensing, including details on licensing virtual machines, see the SQL Server 2016 Licensing Datasheet. You can find even more detailed licensing information information in the Microsoft Product Terms document.. UpgradingFor information about upgrading from previous versions of SQL Server, see the SQL Server Supported Version and Edition Upgrades. If you have active Software Assurance for your SQL Server licenses, you don't need to request the new version of SQL Server through TechSoup. You can simply download the new version through the VLSC to upgrade, and it won't count as an additional title toward your two-year title limit.CALs work for the version equal to or earlier than their server software. They must be upgraded for use with newer server software. If you upgrade to the next version of SQL Server, you will also need to use Software Assurance to upgrade the CALs or request new CALs.
