Microsoft announced Premium Assurance which is a way of adding six more years of product support for either Microsoft Windows Server or Microsoft SQL Server. Microsoft Premium Assurance will be available in early 2017.
Here are the key facts that you need to know: you need Software Assurance (SA) to be able to purchase Premium Assurance, and you must purchase it for all servers with active SA in an Enterprise Agreement (EA), Enrollment for Education Solutions (EES) or Server and Cloud Enrollment (SCE). You also need to acquire Premium Assurance for a product before it goes out of support, and the price will go up over the next few years – from March 2017 it will be 5% of the license cost rising to 12% from July 2019.
