How often do you replace your smartphone? One year, two years or three years. As new technologies keep churning out more powerful processor chips, hardware and better memory management, it becomes inevitable to swap your existing smartphones with more powerful ones that do offer a lot more edge over the old ones. Same case applies to business IT systems and applications. Organizations spend huge money in setting up their IT systems. Nevertheless, there comes a time when every business enterprise must upgrade to newer versions or replace their legacy systems with more agile cloud technologies.
