Analyst(s): Consult the Board Research Team


This summary contains input from twenty-six members regarding the migration of legacy applications to the cloud. We begin this summary by examining the percentage of members' application portfolios they consider to be legacy applications, the percentage of these applications they expect to migrate to the cloud, and members' overall approaches to legacy modernization. Next, we analyze and review the initiatives members have undertaken to educate their CEOs and boards of directors regarding investment in cloud-based legacy modernization. We then discuss members' approaches to calculating the ROI of migrating legacy systems to the cloud and examine how actual ROI has compared with expected ROI. Finally, we close this summary by identifying the primary benefits, challenges, and learnings respondents identify based on their experiences migrating legacy applications to the cloud, both from a technical and organizational perspective.
