Case Studies

Consolidating a Sprawling VAX and Alpha Estate onto Modern Servers

A U.S. naval research center collapsed fourteen aging VAX and Alpha machines onto a handful of modern servers — preserving its full software investment while improving performance across every node.

Modernizing a Defense-Critical Alpha System Without Touching the Application

A major aerospace and defense contractor eliminated end-of-life Alpha hardware risk while preserving its entire software investment — with zero application changes and a 10× cut in power and cooling.

Bringing Decades-Old VAX Systems onto a Modern, Supported Platform

A global aerospace and industrial manufacturer retired two decades-old VAX machines for modern emulation — boosting CPU performance up to 20× while preserving its entire software investment.

Acid Room Control System Modernization

A leading defense contractor replaced unsupported, end-of-life acid room controls with a fully supported modern Siemens platform — delivered in 12 weeks with only three days of onsite work.

vtAlpha Application Level 3 Support

Network outage, switch failure, IP reconfiguration, VMS systems unreachable, no internal OpenVMS expertise

Rebuilding a Legacy System in Modern Code While Preserving Operational Fidelity

Obsolete custom hardware (ISA bus), fragile undocumented codebase, hidden cross-layer

Migrating a 30-year-old Database to a Modern Application Stack

Unsupported database, no modern driver compatibility, data trapped in obsolete platform, no upgrade path, emulated infrastructure

Legacy SCADA Replacement for a Tier 1 Industrial Manufacturer

End-of-life SCADA/HMI, DOS-based control interfaces, unsupported legacy code (FORTRAN/C), extreme uptime requirements, no modern integration path

Tank Farm Industrial Control System Automation: Bridging Operations and Enterprise Systems

Data silos, manual inventory tracking, disconnected Access database, no real-time visibility, compliance/reporting gaps

ABNet Communication Software for VMS-to-PLC Ethernet Communication Case Study

Aging VAX hardware, serial communication bottleneck (RS-232), single points of failure, no path to modern PLCs, rare/retiring technical staff

Virtualizing Legacy Alpha Systems

End-of-life hardware, expiring support contracts, hardware failure risk, 24/7 uptime requirements, large-scale data migration
