Run your existing OpenVMS VAX systems on modern hardware, virtual machines, or the cloud — with no code changes, no recompiling, and no retraining.
vtVAX is a high-fidelity software emulation platform that replaces legacy DEC VAX hardware with a hardware-independent solution. It recreates the exact system environment your applications expect, allowing your operating system, user interfaces, and layered applications to run completely unchanged.
Compatibility is verified using DEC’s own diagnostic and architecture validation tools, making vtVAX a proven solution for mission-critical and real-time industrial systems.
VAX environments continue to power critical operations, but the hardware they rely on is reaching its limits.
vtVAX eliminates dependency on physical VAX systems by moving your environment to modern x86-64 infrastructure.
Your applications continue to run exactly as before, but now on reliable, supported hardware with significantly improved performance and flexibility.
