This document discusses the process of migrating data from legacy clinical trial management systems (CTMS) to a new CTMS. It covers four key phases: determining the purpose and benefits of migration, scoping which studies and data types to migrate, evaluating methods for migration, and considering the optimal timing. The presenter outlines factors to examine like available tools, staff resources, data volumes and complexity, budget, and CTMS rollout strategy. The goal is to take a comprehensive, study-by-study approach to analyze needs and choose the most suitable migration path.
