At GreenCore, we recognise that many organisations still rely on legacy platforms to support critical operations. Systems such as Oracle Solaris, IBM AIX, and OpenVMS continue to run essential workloads in industries where reliability, uptime, and compliance are paramount. However, the decline in vendor support, rising costs, and lack of in-house expertise can make managing these systems increasingly difficult.

Our Legacy Systems Support services are designed to help you maintain continuity while preparing for the future. We provide:

• Expert maintenance and administration
for Solaris, AIX, and OpenVMS environments, ensuring stability and security even as vendor support diminishes.
• Custom support contracts
tailored to your operational requirements, with proactive monitoring, patching (where available), and incident response.
• Integration with modern IT ecosystems
bridging legacy workloads with open source solutions, virtualisation platforms, and containerised environments.
• Strategic migration planning
enabling a smooth transition from proprietary legacy systems to modern open source platforms such as Debian GNU/Linux, FreeBSD, or OmniOS.
• Risk management and compliance
ensuring that legacy environments continue to meet organisational and regulatory obligations during the transition period.

Whether your goal is to extend the life of existing infrastructure or to phase out proprietary platforms in favour of modern, open, and cost-effective alternatives, GreenCore provides the expertise to deliver a structured and dependable path forward.
