The rationalization and update of legacy systems can be difficult tasks requiring a great deal of IT time, management commitment, and company expense. However, some insurers in the life and property/casualty industry in London that migrated data from legacy systems found the benefits of increas-ed efficiencies, long-term cost savings, and enhanced management information systems are well worth the effort. Among the various challenges they faced were data cleanup and legacy systems creat-ed as a result of mergers and acquisitions. The following case studies de-scribe the hurdles they encountered and how they overcame them to achieve their goals.

(When Clegg was interviewed, he was Prudentials program manager. At the end of April, his contract with Prudential ended and he is currently freelancing for other companies.) The program, completed in 2001, involved moving old data onto a smaller, more flexible, and robust client services system, which provided additional functionality for further growth, says Clegg.
