Under the new policy, which starts June 1, customers will still get at least five years of mainstream support after the date a product ships, but the support period now automatically extends for two years after the next version of the product ships. This could result in more than five years of mainstream support.Under the new policy, after mainstream supports ends, Microsoft will provide extended support for five years or for two years after the second successor product ships, whichever results in the longest support period, the vendor said. By "second successor" Microsoft refers to the second major upgrade of the product."This is designed so that we never have less than two years for a customer to migrate to the next version," said Peter Houston, a senior director at Microsoft. "Customers can now predict in advance how long they are going to get support even if they don't know when the next product is coming out.""With something like SQL Server 2005 the challenge was that without this updated policy, mainstream support for SQL Server 2000 might have ended before customers were able to migrate," he said.SQL Server is Microsoft's database product. SQL Server 2005 is due out in the first half of next year. Mainstream support for the current SQL Server 2000 software was set to end on Dec. 31, 2005, potentially giving customers only months to upgrade before the end of mainstream support.Windows XP was another issue, Houston said. Mainstream support for the operating system was set to end Dec. 31, 2006. The next Windows client, codenamed Longhorn, is expected in 2006, which would give customers little time to migrate within the first support period.Mainstream support includes all the support options and programs Microsoft offers, such as no-charge incident support, paid incident support, support charged on an hourly basis, support for warranty claims and hotfix support.In the extended support period, Microsoft still offers all paid support options and security fixes, but won't accept requests for warranty support, design changes or new features. Also, hotfix support not related to security issues requires a separate Extended Hotfix Support contract.The updated support life-cycle policy is valid for Microsoft's business and developer products that are currently in the mainstream support phase as well as future products, the company said. The policy does not apply to consumer, hardware, multimedia and Microsoft Business Solutions products."Any business and developer product that is currently under mainstream support will fall under the new policy," Houston said. An example is Windows 2000, he said. Versions of Windows and Office specifically for home use, such as Windows XP Home Edition, don't fall under the policy, he said.Users of business and developer products currently in the extended support phase may also benefit from the change on a per-product basis, Microsoft said. Any support policy changes take into account product road maps, customer migration needs and industry standards and requirements, the vendor said.Microsoft has faced repeated criticism about its product lifecycle policy. In October 2002 the Redmond, Wash., vendor revised its product lifecycle and applied it to products released after that date as well as select operating systems that were released earlier, including Windows 2000 and Windows XP.The October 2002 change did not apply to Windows 1998. Days before Microsoft was to end support for Windows 98 and Windows 98 Second Edition early this year, the vendor, as a result of user revolt, decided to extend the life of the products in the extended support phase.The product support extension is an acknowledgement of the fact that customers aren't upgrading products as fast as they used to, said Peter Pawlak, a senior analyst at Directions of Microsoft, a research firm in Kirkland, Wash."Products aren't turning over as much as they used to, so Microsoft finally decided that they would just have to move up the general support time," he said.More information on the updated support policy can be found on Microsoft's support life-cycle policy Web site.
