Why Legacy Modernization is Crucial for Business Success
Aug 06 2019


Technology is undergoing radical changes. This requires businesses to review their existing IT infrastructure and consider legacy modernization, if the systems are inefficient to meet the new challenges.

Deciding for legacy system modernization is often the most challenging part of the whole process, as there are several misconceptions around legacy modernization.

Why Organizations Show Reluctance to Legacy Modernization

Organizations are often reluctant to change and keep clinging to a legacy system, mainly because of the following reasons:

1. Familiarity with the system: Employees and users are familiar with the system and like to stick to what they understand.

2. Replicating a labyrinth of codes and integrations: As the system has been used for a long time, it contains customized business processes, code, and integrations, and replicating those into a new system is complex.  

3. Risk of loss and downtime: Critical business operations are run on a legacy system, replacing which can lead to downtime or high business cost.

4. Myopic analysis of cost: Often businesses fail to correctly estimate the cost of maintaining a legacy system. Due to the myopic analysis of the operation and maintenance cost, businesses often refrain from adopting a newer system.

A collaboration between business and IT leaders is required to find out what is holding back the business and what would be the best approach to resolve the problem.

The biggest misconception that replacement is the only option for legacy modernization. It isn’t. According to Gartner, there are multiple options to modernize legacy systems, ranging encapsulation to refactoring and rearchitecting to rebuilding.      

How Delay in Adopting Legacy Modernization Can Affect Your Business

Delay in adopting newer system may prove fatal for your business. Remember Nokia’s failure in the marketplace?

Nokia’s decision to not go with Android as a replacement for Symbian is a constant reminder that even the best of businesses can be wiped out from the market if they fail to embrace the latest technology on time.

Not to replace Symbian was a strategic decision for them that resounds how crucial is decision-making to business growth and success. Almost near to extinction, Nokia has made a dazzling comeback in the market recently through the right partnership and by embracing new technologies.

Dig out the market and you will find many such companies lying underneath the piles of legacy software, either have failed or on the verge of failure.

The Benefits of Legacy Modernization

Removing an obstacle from the growth trajectory could have many approaches lying in between encapsulating the data and functions of an application to eliminating the former application components and replacing it with a new one.

Business and IT leaders are required to work together and create a legacy modernization strategy necessary to boost accelerate innovation.

Here is the list of key benefits of legacy modernization:

  • Increased efficiency: Application modernization is necessary in today’s scenario to achieve a highly flexible system with better usability and event-based functionality. Through application modernization, businesses can migrate their assets on cloud, assuring better integration capabilities and functionality.
  • Reduced Complexity: Rearchitecting the system with better code and integrations can help organization clean the application and reduce complexity. A simple example could be the COBOL code, which is getting difficult to manage, as the mainframe is more than four decades old.
  • Enhanced Compliance: A company which is compliant to industrial regulations is better able to generate trust among users. Through legacy system modernization, organizations can achieve real-time accessibility to the latest applications, increase security, and improve accuracy, and maintain easy data entry, and track the level of compliance with the industry.

Legacy system modernization is extremely important to sail through the challenges that a competitive market bring through. In the modern times, businesses need to align their IT and operation, which is possible through creating effective legacy system strategy and implementation.
