Legacy Systems

Practical Support for Modern Business Needs

Nelop Systems offers expert support for your critical legacy IT, ensuring systems that can’t be discarded continue to run securely, compliantly, and with minimal disruption. Our Legacy Systems service covers everything from ageing operating systems to proprietary hardware and mission-critical applications that no longer have vendor support.

We don’t believe in forcing wholesale rewrites. Instead, we specialise in preserving what works, replacing what fails, migrating what’s possible, and protecting what cannot move.

Protecting the Technology You Rely On

Here’s what Nelop Systems offers in our Legacy Systems portfolio. Each service is tailored to work around your existing architecture and minimise disruption:

  • XP Support & Migration
    Keep your Windows XP environments alive beyond end-of-life. Nelop can transition these systems onto modern hardware or into virtual machines while keeping your original applications unchanged.

  • COBOL on Linux
    If you're running COBOL on expensive legacy platforms or mainframes, we help you migrate to Linux. Preserve your business logic but gain cost efficiency, flexibility, and modern infrastructure support.

  • Legacy UNIX Systems
    For organisations still dependent on AIX, Solaris, HP-UX, or other legacy UNIX variants, we offer support, extended maintenance, and migration planning to more modern platforms or Linux.

  • DOS & OS/2 Applications
    Whether it’s utilities, control systems or custom‐built tools, we can preserve, virtualise, or emulate DOS or OS/2-based applications so your operations continue without rewriting or losing functionality.

  • Hardware Replacement
    Ageing physical components are a big risk. We source, refurbish or replace failing boards, storage, controllers, and other bespoke hardware to avoid catastrophic failure or loss of service.

  • Air-Gapped System Security
    For systems that must remain isolated (for security, regulatory or operational reasons), we provide hardened protection, monitoring and maintenance strategies to avoid exposure, even without regular updates or direct internet connectivity.

  • Regulatory Compliance
    Legacy systems still in operation may fall foul of regulations (health, finance, defence, etc.). We audit, document, and guide you to maintain compliance, risk management, and audit readiness—even where vendor support has ended.
