Migrating legacy Unix systems such as Solaris Zones to modern cloud-based infrastructures presents technical, operational, and performance challenges. As many enterprises seek to modernize legacy workloads while ensuring business continuity, understanding the performance trade-offs of such migration is crucial. This study presents a structured performance benchmarking model for migrating Solaris Zones to AWS-hosted Linux virtual machines. The model evaluates key metrics--including latency, throughput, and system stability--both pre- and post-migration, offering empirical insight into the performance implications. Results indicate that while Linux VMs on AWS demonstrate significantly improved throughput and maintain comparable system stability, certain workloads experienced increased latency due to virtualization and I/O differences. This paper provides actionable benchmarks and migration strategies to guide infrastructure modernization efforts in Unix-heavy enterprise environments.
