Legacy System Modernization

Why Modernize?

One of the most serious obstacles to digital transformation is the use of legacy systems. Lots of organizations continue to rely on outdated technology that lacks a reliable support system, and is unable to satisfy organizational needs. There is a misguided belief that the old system can still efficiently handle the job, while others believe that it would be too expensive and risky to fully modernize their systems.
While these concerns are valid there are many reasons why your company should consider modernizing.

Challenges of Legacy Systems

Lost business opportunities
Legacy systems entail expensive maintenance and a lack of organizational efficiency and agility
Stopping innovation
If your system is outdated, then you are lagging behind modern technologies, as well as reducing the level of security of your system
Regulation violations cause fines
A legacy system may not comply with the new evolving rules

Benefits to Modernizing

Improved technological relevance
An upgraded system improves reliability and performance
Improved business environment
The new system gives a competitive edge and enriches your staff’s experience
Future Proofing
The upgraded system will serve you for a long time, and it will be possible to integrate other work systems

Approaches to Legacy Modernization

Depending on different legacy system modernization considerations, various approaches can be utilized to achieve digital transformation. They include:

Migration and Enhancement

This typically involves re-hosting or using cloud solutions to modernize or enhance legacy systems without changing the current business logic and architecture. Migration may include UX/UI updates.

Correction and Growth

This approach assumes that the current system is relatively modern, and merely requires updates and optimizations. No significant changes in business logic are made.

Total Transformation/ Software Reengineering

This approach draws from the revolutionary method of legacy modernization and involves reengineering the logic of the system. The legacy system is used as the basis while new technologies are used to make improvements.

Legacy Modernization Methods

Legacy system modernization can affect several different facets of technology, including, applications/software, languages, database, technical architecture, platforms, systems, presentation layers, functionality, and so on. Whether the legacy system modernization affects one or more facets, different methods can be used to realize digital transformation goals.

Revolutionary Method
The method seeks to replace a legacy system by reverse-engineering the current system and reconstituting it into modern architecture. The old legacy system is shut down, and a new system is built from the ground up.
Evolutionary Method
The method involves adding a new technology layer to conceal the legacy system. The evolutionary method is not disruptive in nature but rather acts as a workaround to solve current problems.
Hybrid Method
It’s possible to start with the evolutionary method for immediate value gains and slowly build-up to a completely reconstituted modern system.
