Legacy System Renewal: Adoption Trends and Economic Experiences

December, 2008


The decision whether to renew or replace legacy applications is an economic one that many IT managers are wrestling with today. In this study, we first assess current adoption and investment rates for legacy system renewal projects, based on our annual survey of about 200 IT organizations. Next, to determine risks associated with legacy system modernization we look at the return on investment (ROI) and total cost of ownership (TCO) experiences of organizations that have undertaken such projects. Finally, we examine trends by organization size and conclude with a summation of our findings and key recommendations. (4 pp., 9 figs.)
