Legacy application transformation

Legacy application transformation is pursued by many modern companies in their search for:

  • Lower infrastructure support costs;
  • New features, flexibility and scalability for existing systems;
  • Increased systems' efficiency, which influences the productivity of the business and end-users;
  • Reduced time to market.

Exigen® Services has been providing comprehensive legacy transformation solutions to enterprises for over a decade. We help clients analyze and rationalize their software portfolios, while using their business objectives to develop the best approach to upgrading, replacing or augmenting the existing functionality of their infrastructure.

With the advent of new flexible open and .NET-based computing standards, many enterprises are taking a new look at legacy application migration as solution to a variety of critical business issues including:

  • High cost of maintaining legacy systems;
  • Inability for systems to address all current business needs including the lack of features/functionality and flexibility/scalability;
  • Inefficiency of systems, impacting the productivity of the business and end-users;
  • Complexity of interfaces and inability to integrate these into new environments;
  • System integration and consolidation;
  • Redundancy of features/functionality existing due to M&A activity and the introduction of new technology;
  • Lack of legacy skills;
  • Sluggish time-to-market with legacy architecture impacting the company's ability to modify systems quickly;
  • Obsolescence of technical platform and design as it relates to the architecture evolution.

Exigen Services provides three basic approaches for legacy transformation. The right approach for your enterprise depends upon your specific business requirements, desired timeframe and budget.

Upgrade Legacy Systems

This approach lends itself to adding new products, functionality and enhancements into the legacy environment with minimal or no introduction of new technology.

Advantages:

  • The business can continue operating as usual
  • Minimal migration and integration costs compared to those in replacing systems
  • Reduced impact on current users

Replace Legacy Systems

This approach provides a complete replacement of existing systems.

Advantages:

  • Utilization of advanced technology
  • Implementation of best-fit features
  • Ability to develop scalable systems for future needs
  • Easier ongoing maintenance

Augment Legacy Systems

This approach extends and enhances legacy systems, integrates new features to other systems, or selectively replaces the legacy application.

Advantages:

  • Reuse of legacy functions
  • Reduced costs due to lack of complete system re-write
  • Ability to deploy only features required
  • Faster time to market than full system replacement
