  • re-engineering
  • interoperability
  • replacement and retirement
  • changes to the application architecture.
What does the application modernization process look like?

The modernization process comprises 5 consecutive steps: first contact, discovery phase, modernization, integration, support, and maintenance.

What is the purpose of Application Modernization Services?

Modernization can open up new business opportunities, increase business agility, reduce operating costs, and provide scalability and top-notch security.

Who works on application modernization?

The modernization team may vary from project to project. Still, the app modernization team usually includes software developers, business analysts, architects, UI/UX designers, QA and DevOps engineers, and a Project Manager.

When should a software system be modernized?

The system needs to be replaced or modernized when:

  • the technology it was built is no longer available
