What is Legacy Systems Modernization?

Legacy systems modernization is the need of the hour. Old systems and software mainframes riddled with technical drawbacks and expensive to maintain cannot commit and deliver to modern business requirements. An advanced, scalable software solution is the need of digital disruption across industries.

Benefits of Legacy Systems Modernization

Operational Efficiency

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


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

Information Technology is a fail if it is not agile & adaptable enough to meet clients’ expectations on time. Legacy systems/software, therefore, need upgradation. Modern systems/software are agile, helping you respond quickly to change.
All said, it speaks volumes when a business decides to take a stand to phase out its old legacy systems/software. It proves that they are client-centric; they will not entertain any disruption on the way to meet their client expectations.

Cloud Migration

When an enterprise deals with legacy systems/software 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 integrates 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 message; the time when you need us!

Sector-Wise Importance of Legacy Software Modernization


Covid19 has been the biggest check for the government sector when around December 2020, 15000+ Vermont citizens received delayed unemployment checks due to some mainframe error. Imagine the horror and then think if upgrading decades-old legacy systems/software 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, carveouts, divestitures, spin-offs, etc. In health care, 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 systems/software is a better fit or investing in art-of-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 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 COBOL from the 60s and 70s. Modern programmers use advanced programming languages (COBOL is now obsolete), and therefore there’s always a risk involved if banks do not consider modernizing their legacy systems/software.
