Retire legacy systems safely — phased migration, validated data cutover and a clean decommissioning plan that closes off old cost and risk.
Legacy systems live forever because nobody plans the retirement. A real migration + decommissioning plan with parallel-run windows, validated data cutover and a sunset checklist is what actually closes old cost and risk.
A senior-led delivery sequence — not a template dump. Each phase is operated with your team, not handed over as a deck.
Inventory legacy systems with dependencies, users, cost-of-keeping and known risks; agree retire / migrate scope with business.
Sequence waves with parallel-run windows; design data-migration architecture, reconciliation and cutover playbook.
Run waves with validated data cutover, user training and explicit sign-off; track defects and reconciliation gap to zero.
Execute sunset checklist, close vendor contracts and capture run-cost recovered; report savings and risk reduction.
