Hopefully by now you are aware that Windows XP is past its end of life support date and will no longer be updated or patched. The same situation is going to occur for Windows Server 2003 next year.
From July 15 2015, Windows Server 2003 will no longer be updated or patched by Microsoft. For companies still using Server 2003 either as a stand-alone product or as part of Small Business Server 2003, now is the time to start planning a migration to a more up to date platform.
Of course 2003 systems will continue to operate, but being unsupported by Microsoft means that mitigation of issues may prove to be very difficult and may, in fact, incur a cost above and beyond any network care plan. This means that if issues or incompatibility do occur after this date, there could be significant heartache and financial costs resolving the issue.
It is simply a fact of life that vendors like Microsoft cannot continue to provide support for software that is now over 10 years old. Technology has simply progressed too far to allow these systems to be retro fitted with many of the technologies that systems require today.
Staying current ensures that you not only have access to all the latest features but it also means that you are covered by support from the vendor and other third party providers. Everything that has been learnt in the last 10 years about things like security and usability has been incorporated into the latest software.
Correct recommends that clients with Server 2003 systems (including SBS 2003) start considering an upgrade of their environment. With end of product support fast approaching, it may be something worthwhile working into your budget for the current financial year rather than next.
