Doomsday is approaching for Windows Server 2003 users and while small organisations have migrated away, large organisations are staying put.

Organisations with more than 200 staff are still reliant upon WS2003 (72%) despite the well documented threat brought about from lack of support.

With the 14th July deadline for end of support having come and gone it seems that the complexities surrounding migrating are proving to be too daunting.

Jon Seddon, Head of Product, Outsourcery, said: "IT projects inevitably involve a degree of complexity, but when we consider how integral Windows Server 2003 has been to businesses’ IT for the past decade, and the layers that have built up on the operating system during that time, the task of moving away from it can be a daunting one.

"This complexity tends to ratchet up in line with the size of a business, so it’s somewhat understandable that the proportion of larger organisations still using Windows Server 2003 hasn’t shown much movement in the run up to the end of support deadline.

"But doing nothing is clearly not an option and those still using the operating system past this week’s 14th July deadline face significant risks to the security of their data, their productivity and the ability to remain competitive."

The lack of security updates for WS2003 means that customers could face increased risks. Many have opted to take a rudimentary incremental upgrade, while others have resorted to refining their IT strategy.

Alex Hilton, CEO, CIF, says the simpler choice is Cloud: "a far simpler and easier option would be to embrace the chance to move the infrastructure workloads to cloud services. The coming months represent a great opportunity for customers to make a cloud migration and adopt the latest enterprise-ready technology in a cost effective manner."
