This document presents the final specification, techno-economic analysis, and migration guidelines for the PREDICT-6G project, which aims to develop a secure, interoperable, and scalable deterministic network architecture for 6G scenarios. It addresses key challenges in multi-domain, multi-technology networks by integrating a multi-domain data plane (MDP) and AI-driven multi-stakeholder inter-domain control plane (AICP) to enable end-to-end deterministic services with enhanced security, reliability, and automation. The techno-economic analysis demonstrates significant cost savings and business opportunities, particularly in smart manufacturing, by reducing total cost of ownership and improving operational efficiency. Migration guidelines provide a phased approach for integrating PREDICT-6G into existing infrastructures, ensuring compatibility and scalability while maintaining strong security measures. Overall, the project contributes to the advancement of 6G technology and supports Europe’s strategic goals in digital sovereignty and industrial competitiveness
