Supplementary Material - Requirements of a Guide to Cloud Migration Strategies for Legacy Software Assets in Software Ecosystems

Supplementary material for the study on defining the requirements of a guide to cloud migration strategies for legacy software assets in software ecosystems (SECO). This work investigates cloud migration strategies within a proprietary SECO (PSECO) and proposes a decision tree artifact to assist IT managers in evaluating migration options. We analyze real-world constraints, stakeholder concerns, and governance requirements through a participative case study in a large international organization.
