On the other hand, application modernization is transforming applications with new standards of technology and programming. Application modernization may include refactoring, re-platforming, rearchitecting, rebuilding, or data migration. Some companies supersede their operating system from scratch to implement a new application to provide a better user experience and fulfill customer needs.
