Windows Server 2003 has been a stable and reliable operating system that enterprises have depended on for years, but it’s coming to its end-of-life shortly. Sound familiar? Companies went through a similar experience with a desktop operating system not that long ago. The experiences that enterprises had during that transition provide some valuable lessons for the current one—for which the stakes are even higher.
As with Windows XP last year, many organizations are postponing the shift until they can no longer avoid it. Web analytics firm StatCounter found that Windows XP’s global market share was still nearly 19% last February, just a couple of months before its end-of-life. Likewise, Softchoice, a Microsoft managed services provider, conducted research through March 2015 and found that 21% of enterprise servers were still Windows Server 2003.
