On July 14, 2015, Microsoft will end support for Windows Server 2003 and Windows Server 2003 R2. Organizations that fail to migrate from Windows Server 2003/R2 before this date will be out of compliance with certain existing business standards and possibly expose themselves to vulnerabilities.
Fortunately, migrating to a supported server operating system can help you mitigate these risks and deliver valuable benefits and efficiencies that are not available in Windows Server 2003/R2. To take advantage of this opportunity, your organization will need a clear understanding of the different on-premises and cloud migration options available.
