What is Legacy Systems Modernization?

Legacy System Modernization is the process of transforming old business systems into a modern infrastructure to gain better operational efficiencies. Old and outdated systems and software mainframes are riddled with technical drawbacks. It is expensive to maintain and cannot commit to and deliver modern business requirements. Businesses need more advanced, scalable software solutions to deal with digital disruption across industries.

Benefits of Legacy Systems Modernization

Operational Efficiency

Modernizing your legacy systems or software will help you remove any bottleneck in the production cycle; it speeds up product and feature releases, improves efficiency for end-users, and ensures standardization of UI/UX and digitization.


In this uncertain global market scenario, businesses have become more meticulous about their expenditure than before. Modernizing your legacy systems or software helps cut unpredictable investment in obsolete technology for good.


Information Technology is a fail if it is not agile & adaptable and scalable enough to meet clients’ expectations. Legacy systems, therefore, need an upgrade. Modern systems are agile, helping you respond quickly to any transformation.


The security of your system is one of the most important factors why you should consider legacy systems modernization. Old systems have higher possibilities of malware attacks and data breaches due to a lack of support from vendors. Modernizing legacy systems will provide you with better security and protection.

Cloud Migration

When an enterprise deals with legacy systems and decides to modernize their infrastructure, they migrate data, applications, or other business elements to an environment of cloud computing, called cloud migration. Cloud migrations are of various types, the most common being the transfer of data and applications from a local, on-premises data center to the public cloud.


Microservices are an architectural style to build applications as a collection of small autonomous services modeled around a business domain. For example, an e-commerce application has Customer Service, Cart Service, and Product Service. Now, APIs or Application Program Interface integrate the services to communicate with each other to process the client’s request.

SaaS Implementation

SaaS or software as a service implementation is how enterprises enable a SaaS offering in a cloud computing environment. For simple SaaS enablement, it can be a self-service provisioning system available via public clouds. However, SaaS Implementation on private clouds may get complex due to business processes, workflows, setup data, user roles and responsibilities, metadata, and custom instructions & error messages.

Sector-Wise Importance of Legacy Software Modernization


Covid19 has been the biggest check for the government sector. Around December 2020, 15,000+ Vermont citizens received delayed unemployment checks due to some mainframe error. Imagine the horror and then think if upgrading decades-old legacy systems could have prevented it? The government sector has no way out but to invest in technology made for today for a better tomorrow.

Healthcare &
Life Sciences

In life sciences, consider patent cliffs, pipeline acceleration, regulatory changes, consolidation, carve outs, divestitures, spin-offs, etc. In healthcare, think about the security of patient data, evolving local care delivery models, interoperability challenges, increasing financial pressures to shift from volume-based to value-based care, and regulatory changes. Now consider if your legacy system is a better fit or investing in state-of-the-art technology.


In the energy sector, despite challenges, companies still spend a majority of their IT budget on maintaining outdated systems, which is costly and produces no profitable output. Maintaining legacy mainframes requires significant power and resources for smooth functioning and it is also detrimental to the environment. For example, producing electricity by leveraging old technologies is counterproductive to the enterprises’ well-being, geography, and population.


For industries that continue to use legacy systems, it is invariably a false economy with huge financial costs, security compromises, commercial consequences, and operational barriers. However, it is the cost of implementing new technology that holds back Manufacturing SMEs from taking the move forward. For a situation like this, instead of canceling the legacy system at one go, businesses can adopt a modular approach to phase out outdated technology in stages.


Legacy banking software is a major constraint, preventing traditional banks from scaling capabilities at par with digital banks. On average, larger incumbent banks have setups written in Common Business-Oriented Language (COBOL) from the 60s and 70s. Modern programmers use advanced programming languages and therefore there’s always a risk involved if banks do not consider modernizing their legacy systems.
