Incremental Application Modernization

Many organizations depend on applications that were built years ago and still play a critical role in day to day operations. These systems often work well enough to keep the business running, but over time they become harder to maintain, more expensive to secure, and slower to adapt to changing needs. Leaders know these applications can’t stay as they are forever, yet the idea of a full replacement feels risky, disruptive, and difficult to justify. Refactoring can seem like a safer option, but it often brings its own costs, delays, and technical constraints that limit real progress. The challenge becomes finding a way to modernize without pausing the business or starting over from scratch. This is where incremental application modernization offers a practical path forward, allowing organizations to reduce risk, improve security, and move toward a modern architecture at a pace that makes sense.

The Solution

CSE’s approach involves modernizing your application in small, manageable parts. Instead of abandoning the legacy application entirely, we maintain and gradually replace it with a modernized version. Both applications coexist in the same ecosystem and share the same URL. This is facilitated by Cloud technologies (Front Door) that can route between separate application services seamlessly. It is further supported by customer Single-Sign-On (SSO) tokens. With this approach, all new features are added exclusively to the Modern Application, avoiding any further burden on the the Legacy Application.

Incremental Modernization Benefits

• Increased Efficiency: The dual-application approach means that all new updates or significant changes can be coded using a modern methodology in a prevalent language.
• Improved Security: By implementing current best-practice technologies, applications benefit from active support in security patching.
• Cost Savings: With incremental modernization, you can avoid costly refactoring expenses and reduce time spent on development and deployment.
