What Is Legacy Application Modernization?

Legacy application modernization refers to the process of updating legacy applications to run on newer computing environments. Methods of legacy application modernization include encapsulation, refactorization, componentization or replacement.

Benefits of application modernization include:

  • Improve application performance
  • Reduce maintenance costs
  • Enable cloud adoption
  • Increase system security
  • Improve user experiences
  • Support future business growth

The problem is many legacy systems grow increasingly challenging and expensive to maintain due to ageing technologies, mounting technical debt and expanding operational complexity.

Velocity modernizes your applications with a strategic approach that minimizes risk and maximizes measurable business value.

FAQ’s

Frequently Asked Questions

The term application modernization describes the process of taking an existing application and modifying it to run on a newer or different platform without sacrificing important business features. 

Not necessarily. Sometimes, applications can be modernized piece-meal so your business can keep functionality they still value.  

Every application is different, but the effort usually depends on application size and complexity, technical debt, integrations, and business requirements. Some projects can be done in a matter of weeks, while larger enterprise app modernization projects can span several months.  

There are many positive outcomes of modernizing your software, like improved application performance, reduced cost to maintain an app, stronger security, improved user experience, scalability, and the ability to adapt to future needs. 

Absolutely! We work with enterprise applications daily that hook into multiple databases, third-party platforms, other internal apps, and automate critical business operations. 

We mitigate risk by using phased delivery, testing environments, data migration strategies, and solid business continuity planning.
