B2B Data Migration Services
Lumiere Systems is a business-to-business (B2B) data migration specialist. We help organizations seamlessly extract, cleanse, and load data from legacy non-SAP systems into SAP S/4HANA, SAP AnyDB, NetSuite, or Microsoft Dynamics without business downtime.
Clean Data In, Zero Downtime Out
From extraction and cleansing to cutover and validation — engineered so the business keeps running.
Non-SAP to SAP S/4HANA Data Transformation
We map, transform, and load data from legacy non-SAP systems — ERPs, spreadsheets, and custom databases — into SAP S/4HANA, SAP AnyDB, NetSuite, or Microsoft Dynamics with referential integrity intact.
- Legacy ERP & custom database extraction
- Field-level mapping & transformation rules
- Referential integrity validation across target systems
Automated Data Cleansing & Deduplication
Pipelines that detect duplicates, standardize formats, validate references, and flag anomalies before cutover — so your new ERP starts clean, not with years of accumulated debt.
- Duplicate detection & merge rules
- Format standardization & reference validation
- Anomaly flagging & data-quality scoring pre-cutover
Zero-Downtime Cutover Engineering
Cutover plans engineered so the business keeps running — staged loads, reconciliation, parallel-run validation, and rollback contingencies that minimize or eliminate operational downtime.
- Staged loads & reconciliation checkpoints
- Parallel-run validation against legacy system
- Rollback contingencies & cutover runbooks
Validation & Audit Trail
Every migrated record is validated and traced — with audit trails that satisfy finance, compliance, and internal audit requirements and prove the migration was complete and accurate.
- Record-level validation & reconciliation reports
- Audit trails for finance, compliance & internal audit
