Data Migration Fundamentals for SAP S/4HANA

Keep this: job aid

Data migration basics card

• Lifecycle: analyze, design, build, mock loads, final load, validate and sign off.
• Migrate master data and open items; leave closed history; build and transport configuration.
• Sequence by dependency: core master, dependent master, open documents, balances and open items.
• Finance: plan the balance approach; migration clearing accounts must net to zero.
• Every selection, mapping and cleansing rule is written down and approved by a business data owner.
• Cleanse at source, early.
• Plan several mocks: technical, full volume, timed, dress rehearsal; measure errors, reconciliation, issues, time.
• Use production-like systems and fresh extracts; freeze rules before final rehearsals.
• Use the Migration Cockpit (Migrate Your Data app): staging tables or direct transfer; simulate before migrating.
• Sign-off is by business data owners, not IT.
