This paper explains the development of the migration process by which applications running on a network of DPPX/SP systems would migrate to a network of DPPX/370 systems. DPPX/SP is a centrally managed, distributed processing system designed to run on the IBM 8100 family of processors. DPPX/370 is the DPPX/SP system ported to the IBM ES/9370 family of processors. The paper outlines the strategies, the technical problems encountered and their solutions, customer participation, and testing. Finally, it provides recommendations on how the process might have been improved.
