Legacy System Migration: Best Practices

Legacy system migration best practices are the strategies and steps that can help ensure a smooth migration process for your business.

Legacy system migration can seem intimidating and expensive, but more organizations are realizing how vital it is for remaining competitive. Despite increasing digital transformation, much of the world still runs on aging mainframe computers. As recently as 2020, 95% of ATMs and many other financial systems still used COBOL—a programming language from the 1950s. Taking a legacy banking system offline for migration would cause severe disruption, so it’s no wonder that decision-makers don’t want to make changes that can affect productivity for days or even weeks.
