The increasing complexity of software ecosystems (SECO) demands effective governance mechanisms to ensure long-term sustainability, particularly within proprietary SECO (PSECO). As organizations modernize their technology platforms, cloud migration emerges as a key strategy to improve scalability, flexibility, and operational resilience. However, selecting an appropriate migration approach for legacy software assets requires a structured decision-making process that aligns with governance principles, business continuity, and technical sustainability. This work investigates cloud migration strategies within a PSECO and proposes a decision tree artifact to assist IT managers in valuating migration options. We analyze real-world constraints, stakeholder concerns, and governance requirements through a participative case study in a large international organization. Our findings revealed that migration decisions are influenced not only by technical factors, such as architecture and performance, but also by business drivers, regulatory constraints, and organizational culture. The proposed guide provides a systematic approach to balancing modernization efforts with risk mitigation, helping organizations avoid technical debt while adapting to evolving industry demands. Using governance mechanisms in cloud migration strategies may support organizations in maintaining platform stability while fostering continuous innovation. Future research should explore how emerging cloud technologies and governance frameworks further impact modernization in the PSECO context.
