Legacy Systems Modernization

Do you face these questions?
  • Requests from my customers are piling up.
  • There seem to be many products offering similar capability. The ones that could be provisioned on the cloud seem to offer incremental costing and quick-to-launch ability.
  • However, there is all this tremendous learning we have in our in-house system that seems to be missing in the commercial offerings in spite of a spiffy user-interface.
  • Do I have a feature bloat that needs to be addressed to rationalize our future investments?
  • Our functionality seems to be inline with our customer expectations, however, I am not confident the technology stack we are built on will support the evolution we intend to pursue
  • Should I invest just on the Ux refresh that will buy me some time with our customers and incrementally patch the backend?
  • Or, should I just ditch the system all together and rebuild from scratch with a totally modern technology stack?
This conversation is all pervasive in enterprises that are supporting mission critical customer functions.

All approaches have different purposes, effects, values, costs, risks and impacts. The answer is more often than not a combination of the available solutions. It is never one versus the other.
Historically, the modernization spend on an application is about 3x the cost of initial development and deployment. This has to be aligned with the greater functional capabilities sought by the various stakeholders.

The following approaches broadly classify the strategy, effort and investments towards application modernization


Provide an API layer on top of traditional applications where years of customer feedback and internal innovation is invested. The complexity of the implementation will be hidden behind the API layer. This ensures a refresh on the look-and-feel without impacting the critical functions.

Rectify & refactor

This is to set up a constant agile process in place to seek user feedback and prioritize the technical debt to refactor the code and be positioned for functional relevance with the stakeholders.

Re-architect and rebuild

This approach is the drastic and bold step of rewriting the application to take advantage of the emerging technologies to completely reposition the product/platform to the forefront of current innovations.

Cloud migration

This offers the ability for the application to be more broadly available without being limited by the constraints of internal IT infrastructure.

Upgrade the technology framework

This is to ensure the application with all its current functions is migrated to the latest stable release of the core framework. For instance, a legacy .NET application may be migrated to the latest release of the framework to take advantage of the performance and security features. This sets for greater longevity of the platform for making future investments into the application with the talent pool generally available.
All of the above require an able partner that has the breadth of experience across a multitude of industries to ensure the stakeholder value is constantly prioritized and delivery risk is mitigated.
