Our SCO UNIX Consulting Services

Many businesses continue to rely on SCO UNIX-derived systems (SCO OpenServer, SCO UNIX, UnixWare) for stable, long-running applications in manufacturing, retail, healthcare, and more. Although mainstream support has evolved, Zwiegnet offers deep expertise to maintain, secure, virtualize, and extend the life of these environments — or guide smooth migrations to Linux.

Our SCO UNIX / OpenServer services include:

System Administration – User management, pkgadd/pkgrm packaging, SCOadmin configuration, filesystem maintenance (vxfs, HTFS), and routine operations.
Security Patching & Hardening – Applying legacy patches, supplements, maintenance packs from Xinuos archives, custom hardening, and risk mitigation for EOL systems.
Performance Tuning – Kernel tuning, process scheduling, memory optimization, and hardware/driver compatibility fixes for aging servers.
Virtualization & Hardware Modernization – P2V migrations, running SCO OpenServer in VMware/KVM/VirtualBox, hardware abstraction, and extending life on modern x86/64 platforms.
Troubleshooting & Break-Fix – Rapid resolution of panics, driver issues, SCOadmin failures, network problems, application hangs, and obscure legacy behaviors.
High Availability & Backup – Mirroring, clustering setups (where supported), tape/backup strategies, and disaster recovery planning for SCO environments.
Scripting & Automation – ksh, Bourne shell, Perl scripting for admin tasks, monitoring, and integration with modern tools where possible.
Extended / Legacy Support Planning – Strategies to safely run unsupported SCO versions, custom patching, and compliance considerations until full migration.
Pre-Migration Consulting – Assessments, roadmaps, and phased transitions from SCO UNIX/OpenServer to Linux (RHEL/Alma/Rocky) with minimal downtime.

Whether you need emergency fixes, ongoing maintenance, virtualization to modern hardware, or help sustaining your SCO system long-term, we provide experienced, hands-on support for these battle-tested but aging platforms.

Located between Madison and Milwaukee, Wisconsin since 2009 — fast local response for Watertown-area businesses with legacy SCO deployments.
