To this end, process required to provide appropriate set steps techniques that minimize risks at same time ensure quality during migration process. Thus, work presents Service-oriented Process for Reengineering DevOps—SPReaD, instantiation mainstream methodology focusing on legacy integrating DevOps aspects developing microservices systems. This has been defined real software project from Brazilian State Department Taxation. results obtained include substantial improvement in main taxation system used by state, including not only code-related metrics but also performance improvements services offered, change adopted development team.
