Abstract: Legacy UNIX systems, including Solaris, AIX, and HP-UX, continue to underpin critical enterprise workloads, yet modern IT demands require integration with Linux and cloud-based platforms. This review examines strategies for unlocking the value of legacy UNIX systems while adopting hybrid cloud and Linux infrastructures. It explores assessment, migration, co-existence, and modernization approaches, emphasizing automation, orchestration, and operational management. Security, compliance, and disaster recovery practices are discussed to ensure reliable and auditable operations across heterogeneous environments. Case studies from large enterprises and mid-sized organizations demonstrate practical implementations, highlighting lessons learned, challenges, and measurable benefits. Emerging trends such as multi-cloud adoption, AI-driven automation, and evolving operating system capabilities are analyzed to guide future-ready integration strategies. This review serves as a strategic and technical roadmap for IT architects, system administrators, and enterprise decision-makers seeking to maximize legacy system value while modernizing operations for scalability, resilience, and innovation.
