A Simulation Model for the Performance Evaluation for Migrating a Legacy System
نویسندگان
چکیده
It would be strategically advantageous to organisations if they could predict the behaviour of the new systems meant to replace existing legacy ones. In fact, these organisations could tackle possible performance problems of the new systems before they become operational. This paper describes how CAPPLES, a capacity planning and performance analysis method for the migration of legacy systems can be used to predict such behaviour. The paper describes the process of constructing, validating and deploying a simulation model using CAPPLES. Peculiarities of the legacy system migration that affects the simulation process are presented through the use of a case study. Finally, guidelines to perform similar simulation studies are also provided.
