We Help You Wind Down Your Mainframe the Right Way
Sunsetting a mainframe environment is one of the most complex and risk-laden projects an IT organization can undertake. Supportmyz provides hands-on sunsetting assistance to organizations that are decommissioning their mainframe — whether you are migrating off the platform entirely, consolidating hardware, or winding down a legacy environment. We have guided organizations through every phase of the sunsetting process and we know where the risks are before they become problems.
Sunsetting Methodology
We assess your full mainframe environment — hardware, software, data, applications, and staffing — to build a complete inventory and identify all dependencies before any work begins.
We develop a detailed sunsetting roadmap with milestones, risk mitigation strategies, cost reduction opportunities, and a realistic timeline aligned to your business requirements.
Our team works alongside yours to carry out the plan — archiving data, coordinating hardware disposition, managing vendor terminations, and supporting application migration efforts.
We ensure a clean and complete decommission — final data verification, hardware removal, contract closeouts, and documentation — so nothing is left unresolved after the last system goes dark.
