CPI works with a collection of systems in flux and can be used to help agencies gradually migrate from legacy systems to the Cúram platform. It achieves this by providing configuration options to turn off or on aspects of CPI. This allows certain types of data to be constant while other types of data are being migrated. For example, CPI can be configured to display person information but not case information. Agencies can focus on migrating person information into the Cúram platform without having to contend with case information. Another benefit is the ability to migrate from legacy systems to Cúram on a program-by-program basis. For technical information on using CPI to support modernization, see the Case Participant Index Developer Guide.
