Nexus expertise in chosen business verticals is a key factor in our ability to successfully execute large re-engineering projects. Also, Nexus has proven capability to develop parsers to extract and forward-engineer business rules residing in legacy applications. Our domain expertise in chosen business verticals is a key factor in its ability to flawlessly execute large re-engineering projects.

Nexus Offerings

Nexus Migration and Reengineering methodology adopts a four-phased approach. Critical to this approach is ensuring continuity and transparency across all phases. This is achieved by using tools that bind and drive the entire project.

Nexus capabilities cover the spectrum of application migration and re-engineering including:

  1. Application Analysis: Analyzing the suitability of an application migration or re-engineering exercise including choice of the target architecture.
  2. Portfolio Analysis:  Analyzing the suitability of re-engineering an entire portfolio of related applications.
  3. Platform Migration:  Migrating an existing application to new hardware, operating system, and database or programming environment.
  4. Application Re-engineering: Completely redesigning an application to provide superior functionality by taking advantage of new technology standards.
