Business Continuity & Risk Mitigation
Ensuring critical applications and data remain continuously available during and after migration is central to every Proxymus engagement. We design and execute migrations with minimal downtime, using controlled cutover processes, parallel run options, and comprehensive validation to protect day-to-day operations.
By removing dependency on ageing and unsupported physical hardware — where spare parts and specialist support are increasingly scarce — we significantly reduce the risk of unplanned outages and operational disruption. Legacy systems are transitioned to resilient, modern platforms without requiring application rewrites or data changes.
Disaster recovery is engineered into the solution from the outset, including automated backups, snapshot-based protection, replication to secondary environments, and clearly defined failover and recovery procedures. This approach ensures business-critical systems remain protected, recoverable, and supportable long into the future.
Performance & Compatibility
Maintaining consistent application performance and behaviour is critical when modernising legacy environments. Proxymus ensures that migrated systems deliver performance equal to or better than the original hardware, while preserving the exact runtime characteristics that business-critical applications depend on.
Through high-fidelity PA-RISC emulation and careful platform sizing, we replicate the behaviour of the original HP 9000 environment without requiring changes to the HP-UX operating system, application binaries, or data structures. This guarantees full compatibility with existing applications, integrations, and downstream systems, including MFG/PRO and other tightly coupled enterprise workloads.
Performance is continuously validated throughout the migration process using real-world workloads, benchmarking, and joint testing with client teams. The result is a modern, resilient platform that delivers predictable performance, seamless interoperability, and complete functional equivalence — without the risks and costs associated with application rewrites or re-certification.
Security & Compliance
Protecting sensitive data and maintaining compliance with regulatory and internal security requirements is fundamental to every Proxymus engagement. We design migration and modernisation projects with security built in from the outset, not added as an afterthought.
Legacy HP-UX environments are transitioned into secure, hardened platforms with encrypted storage, controlled network segmentation, and strict access controls aligned to modern security best practices. Identity management, logging, and audit capabilities are enhanced to improve visibility and accountability, while preserving existing application behaviour and access patterns.
Compliance requirements are supported through documented architectures, repeatable deployment processes, and verifiable controls covering data protection, backup retention, and recovery procedures. This approach enables organisations to meet regulatory, governance, and audit obligations with confidence, while significantly improving their overall security posture compared to ageing, unsupported physical systems.
Cost Efficiency and Sustainability
Modernising legacy HP-UX environments is as much about long-term cost control as it is about technical resilience. Proxymus helps organisations reduce ongoing operational expenditure by eliminating reliance on expensive, power-hungry, and increasingly unsupported physical hardware, while extending the usable life of existing applications.
By transitioning workloads to virtualised or cloud-based platforms, clients benefit from predictable infrastructure costs, improved resource utilisation, and the ability to scale capacity in line with real business demand rather than fixed hardware constraints. This removes the need for costly emergency maintenance, spare-part sourcing, and specialist hardware support contracts.
From a sustainability perspective, consolidating legacy systems onto modern infrastructure significantly reduces energy consumption, physical footprint, and hardware waste. The result is a more environmentally responsible platform that supports long-term operational planning, budget predictability, and future modernisation — without forcing disruptive application rewrites or wholesale system replacement.
