METHODOLOGY REFERENCE
A migration & cutover playbook I authored, showing how I’d sequence data load and run a go-live. The cutover discipline is real — I’ve executed it across four XeerSoft go-lives — framed here in SAP S/4HANA terms; it is not a record of a delivered SAP migration.

Data Migration & Cutover

Go-live is won or lost in the data load and the cutover window. This is the discipline I run: a migration-object catalogue with the right load sequence (master before transactional), a T-minus cutover runbook you can step through, and the go/no-go reconciliation gate that decides whether the system goes live. Framed in SAP S/4HANA Migration Cockpit terms, built on four real ERP cutovers.

01 · What loads, and in what order

The migration-object catalogue.

You cannot load an open invoice before the customer exists. Every object has a type and a load sequence — master data first, then the transactional open items that reference it. Filter the catalogue below.

Org structure & config travel by transport, not the Migration Cockpit — they are the container everything else loads into.

02 · The cutover window

Run the cutover.

A cutover is a countdown: freeze legacy, extract, load, reconcile, decide, open. Press Run cutover to walk the T-minus sequence, or step it yourself.

    03 · The decision gate

    Go / no-go: every box, or you don’t go.

    Cutover ends at a gate. These are the criteria I’d hold the line on — tick each as it clears; the verdict flips to GO only when they all do.

    ABOUT THIS RUNBOOK

    The migration objects, load sequence and cutover phases are the standard SAP mechanism; the go/no-go criteria are the ones I hold to. I’ve run this cutover discipline for real on four XeerSoft Cloud ERP go-lives — freeze, migrate, reconcile, decide, hypercare — and this is how I’d carry it onto an SAP programme. It is a methodology artifact, not a delivered SAP migration.
