In this study, the aim is to create and improve a methodology for synthesizing requirements and specifications for the re-engineering of IT projects with maximum efficiency and business orientation. The main task is to adapt outdated IT systems to the changing technical environment, in particular to cloud technologies and security system requirements. To achieve these goals, the proposed methodology uses the analysis of archaic systems, the reverse engineering method, expert surveys, documentation analysis, and black-box modeling.
