System Migration Plan
The move is not finished when the data arrives — it is finished when nobody wants the old system back.
What it is
The software change treated as what it is — a data decision and a habit decision wearing a project's clothes. Forces the outcome to be stated as a business result before a licence is signed, maps every field and every integration to an owner, cleanses before loading rather than after, and fixes the freeze, the rollback deadline and the reconciliation tolerance in advance. Then carries the work past go-live into adoption, the old system's read-only afterlife and a ninety-day verdict. For operators, finance leads and founders moving a CRM, ERP or payroll system without a project office.
What you receive
a move to a new system that loses neither the data nor the team — the readiness decision with the outcome it is judged by, the field-by-field data map with the rot named before it is carried across, the cutover with its freeze, its named go/no-go signatories and its expiring rollback, the parallel period with its reconciliation tolerance, and the adoption and close-out work that decides whether the system is used
