There is nothing more comfortable than an old pair of worn-in shoes but how long will you keep wearing them? No matter how much you hate throwing them away you must buy a new pair. The same goes for your legacy systems, as comfortable as your business is with them, you know that they do not have the security to meet today’s risks, neither do they have the features that can leverage new technology. You need a legacy system modernization or your business will be left behind.

The high cost of running with legacy applications

The key to success for any business is to keep up with innovations and modernize rapidly. This is the only way to ensure businesses outperform competitors and continue to delight customers. In this race to scale up, a company’s internal software can either be a hindrance or a key driver of growth. Most companies today rely on legacy software that is often developed internally and built along rigid frameworks. These softwares also require regular maintenance by a specialized IT department. The financial and technological restrictions legacy software pose can often compel businesses to consider leaving them behind entirely in favor of newer more agile options available in the market.

An ‘all or nothing’ approach can come with its own set of drawbacks. Legacy systems often have decades of invaluable data stored on them and an entire company’s processes are built around them. Removing them completely can disrupt your existing workflow and could even cause data lapses if the migration is not done correctly.

A far more practical legacy system modernization approach would be to consider an application modernization in a phased manner and retain as many of the useful features of the current software as possible.
