SAP Data Migration to S/4HANA — Validated, DMC-Ready
Migrating to S/4HANA is only as good as the data you bring. deKorvai extracts from ECC, profiles and cleanses, transforms to the S/4HANA model, validates, and loads into DMC staging — so data lands accurate, complete, and ready, across Greenfield, Bluefield, and GROW approaches.
every run monitored · every record audit-logged, source to target
SAP S/4HANA data migration moves data from legacy SAP ECC into S/4HANA. The hard part isn't moving data — it's making sure what lands is accurate, complete, and mapped correctly to the new model.
deKorvai runs the full data path: rule-based extraction from ECC, profiling and validation, transformation to the S/4HANA model, and loading into DMC staging tables — validating before load so the migration lands clean.
A migration is only as good as its data
Move data to S/4HANA without cleaning and validating it first, and you carry every legacy error into a brand-new system — where it's harder and costlier to fix.
Legacy data is dirty
ECC data has accumulated duplicates, gaps, and inconsistencies over years. Migrated as-is, it corrupts S/4HANA from day one.
The model changes
S/4HANA's data model differs from ECC — vendors become business partners, structures shift. Data has to be transformed, not just copied.
Errors surface at load
Without validation up front, problems appear during DMC load, stalling the migration and forcing rework.
Only migrate what matters
Not every legacy record should move. Deciding what to migrate needs checks against real business activity.
The full data path into S/4HANA
Rule-based extraction
Extract data from source ECC based on extraction rules — full or selective.
Profiling & validation
Mandatory-field checks, duplicate detection, and anomaly checks against the target system.
Active-record checks
Check records against real business activity (e.g. PO/GR/IR/FI line items) to decide what migrates.
Transformation & mapping
Map to the S/4HANA model — company codes, org structures, account groups, BP roles.
Validate before load
Pre-load validation and staging so errors are caught before they reach the target.
DMC staging load
Load into the S/4HANA DMC staging tables, then simulate and migrate.
Scrambling for clones
Mask data for sandbox and QA clones used during the migration.
Reconciliation
Reconcile migrated data against the source to confirm accuracy and completeness.
Fits your migration path
New implementation
Selective extraction from legacy, clean transformation to the S/4HANA model, and strong profiling to fix quality issues up front.
Selective data transition
Hybrid data selection — keep what matters — with complex transformation across entities and simulation cycles before cutover.
SAP GROW programs
Supports SAP GROW programs, including meeting tight timelines for legacy data loads.
Extract → Profile → Transform → Load → Migrate
Extract
Rule-based extraction from ECC.
Profile
Mandatory, duplicate & anomaly checks.
Transform
Map to the S/4HANA model.
Load
Into DMC staging, then simulate.
Migrate
Migrate & reconcile against source.
Land clean, on time
Accurate from day one
Validation before load means S/4HANA starts with clean, correct data — 100% accuracy on the BP vendor migration.
Faster cutover
High DMC first-pass rates and 3x faster lead time reduce rework and delay.
Migrate only what matters
Active-record checks keep dead legacy data out of the new system.
Safe non-prod clones
Scrambling protects sensitive data in sandbox and QA environments during the project.
