Large enterprises spend a large portion of their Information Technology (IT) budget on maintaining their legacy systems. Legacy systems modernization projects are a catalyst for IT architects to save cost, provide new and efficient systems that increase profitability, and create value for their organization. Grounded in sociotechnical systems theory, the purpose of this qualitative multiple case study was to explore strategies IT architects use to modernize their legacy systems. The population included IT architects in large enterprises involved in legacy systems modernization projects, one in healthcare, and one in the financial services industry in the San Antonio-New Braunfels, Texas metropolitan area in the United States. The data collection included interviews with eight IT architects, reviewing 12 organizational documents and pertinent artifacts. Data were analyzed using thematic analysis. Prominent themes included collaboration in modernization projects, systems and process documentation, and resources upskilling and technical training. A key recommendation is for IT architects in large enterprises to ensure that team collaboration, system documentation, and resource technical training are built into all aspects of the legacy systems modernization projects. The implications for positive social change include the potential to bring together individuals with diverse backgrounds and different perspectives and skills to develop trust and build positive relationships during legacy systems modernization projects.
