As that old sage Yogi Berra once said, \u201cIt\u2019s like deja vu all over again.\u201d Last year around this time everyone was gearing up for End of Life for Windows XP, a popular OS to say the least. Now it\u2019s 2015 and time to bid adieu to another popular operating system. Windows Server 2003 and 2003 R2, still widely used, will be coming off Extended Support on July 14 of this year. Time to start thinking about retiring those older servers. You might also be interested to know that Mainstream Support for Windows 7, Windows Server 2008, and Windows Server 2008 R2 expired on January 13, 2015.\n\n\nMicrosoft Software Support RoadmapNote: the \u201cExtended Support Phase\u201d (the conclusion of which is often referred to as \u201cend of life\u201d) includes the following: Fee-based Support (now $499 per incident), Security Updates, and Hotfixes. So the basic difference between Mainstream and Extended Support is that with Extended Support you only receive Security-related updates\u2014no Service Packs or non-security updates. Mainstream Support covers the 5-year period after a product is released; Extended Support typically covers the 5 years after the expiration of Mainstream Support. Also note that in either support phase, Microsoft will only provide support for the most recent Service Pack. So with all of this in mind, let\u2019s look at some upcoming support end dates:\n\n\nEnd of Life\n\n\nSQL 2005\u2014Extended Support ends on April 12, 2016\nExchange Server 2007\u2014Extended Support ends on August 11, 2017\nSharePoint Server 2007\u2014Extended Support ends on April 11, 2017\nOffice 2007, Visio 2007, Project 2007\u2014Extended Support ends on October 10, 2017\nWindows Server 2008 and 2008 R2\u2014Extended Support ends on January 14, 2020\n\n\nEnd of Mainstream Support\n\n\nWindows 7 (yes, THAT Windows 7)\u2014Mainstream Support ended on January 13, 2015\nWindows Server 2008 and 2008 R2\u2014Mainstream Support ended on January 13, 2015\nExchange Server 2010\u2014Mainstream Support ended on January 13, 2015\nOffice 2010\u2014Mainstream Support ends on October 13, 2015\nSharePoint 2010\u2014Mainstream Support Ends on October 13, 2015\nLync Server 2010\u2014Mainstream Support ends on April 12, 2016\n\n\nMake sure you are keeping these dates in mind as you plan your next deployments. The end of a support phase should not be your only criteria for making the decision to upgrade, but it should play a role in your decision-making process: you need to assess your risk tolerance, particularly if you are running an older version that will no longer be receiving security patches. Of course there are plenty of other factors to consider when evaluating your deployment roadmap.
