Frequently Asked Questions

  • What are legacy systems?

    Legacy systems are old, outdated business technologies and processes that are critical to business operations. A legacy system is limited to the tasks for which it was originally designed, and is typically unable to integrate with newer, modern business systems.

    Examples of common legacy systems include Lotus Notes, Domino, and SAP ECC.

  • What is legacy modernization?

    Legacy modernization is the process of updating and optimizing business systems to improve operations. As an integral part of digital transformation, legacy modernization is an investment that organizations make to build more powerful, future-proof applications.

  • How do you modernize legacy applications and systems?

    There are several ways to approach legacy modernization. The best option for your organization will depend on the challenges you’re facing and your goals for the future.

    Gartner recommends evaluating your existing legacy systems to determine the business and IT drivers for modernization. Then, you can determine if encapsulation, rehosting, replatforming, refactoring, rearchitecting, rebuilding, or replacing the system will offer the greatest value.

  • Should legacy modernization be handled through the normal refresh cycle?

    Not always. In many cases, legacy systems can be modernized through new components or new software. But this process should proceed according to the enterprise’s requirements, not a vendor’s support schedule.
