The most popular digital transformation initiatives for IBM i shops, according to IDC’s survey.

IDC questioned all four cohorts (IBM i shops that modernized, IBM i shops that migrated, System z shops that modernized, and System z shops that migrated) about their satisfaction across a range of metrics before and after their move, including: customer experience; overall performance; security, availability, and disaster recovery capabilities; agility, microservices, and DevOps; ease of finding talent; ability to incorporate AI and IoT; and API, mobile, and Web enablement.

Across all seven metrics, the IBM i and System z shops that modernized their “legacy” systems scored higher than their IBM i and System z colleagues who chose to migrate off their systems. What’s more, organizations that modernized instead of migrated reported paying less on hardware, software, and staffing, and reported higher revenues to boot.

Making software better rather than just lifting and shifting it usually works out better.
