Microsoft will end support for Windows Server 2003/R2 on July 14, 2015. According to Forrester Report: Economic Impact of migrating to Windows Server 2012 R2, migrating to Windows Server 2012 R2 can significantly improve your server farm efficiency, reliably, productivity, and reduce IT cost.

Improved storage efficiency and reliability with new storage scenarios saving $45,000 to $243,000 per year. With the rapid growth of storage within the data center, organizations found Windows 2012 provided greater data deduplication and storage management with features such as the active-active file server clusters for transparent failover, reducing storage needs by an average of 33%.

Increased productivity — server administration benefits of $541,000 per year. Windows Server 2012 also provided many organizations with the opportunity to increase their virtualization and virtual desktop infrastructure (VDI) footprint, allowing staff to do more with the same amount of resources.

Reduced IT infrastructure spend of $922,000 per year. Driving down infrastructure costs was a key benefit for many of the interviewed organizations. Windows Server 2012 improved the efficiency of spend on infrastructure, cooling, software, power, and hardware through the ability of organizations to reduce physical servers in a virtualized environment.

Greater end user productivity benefits of $203,000 per year. BranchCache and DirectAccess within Windows Server 2012 allowed organizations to derive additional savings by providing added levels of support to selected end users.

Improved application and web development productivity of $310,000 per year. For organizations that used Windows Server 2012 as part of their web applications, these organizations saw increases in developer productivity.
