Move directly from legacy ECC BDM to VSS in a single, seamless step. Cut your project timeline, eliminate transitional environments, and protect business continuity with Near Zero Downtime.
For automotive manufacturers, importers, and dealers running SAP's legacy Dealer Business Management (BDM) module, the path to S/4HANA has historically looked daunting. Two migrations in one – first off BDM, then of SAP ECC onto S/4HANA – with all the data complexity, downtime risk, and project cost that implies.
That challenge is now a thing of the past. Natuvion's data transformation and migration toolset enables organizations to transition from SAP BDM directly to the modern Vehicle Sales & Service (VSS) add-on by Pro Axia – in a single, controlled migration step – as part of a full ECC to S/4HANA program.
The challenge: BDM in a Post-ECC world
SAP BDM has served the automotive sector well as the de-facto dealer management solution within the SAP ecosystem. But with SAP ending mainstream maintenance for ECC and repositioning S/4HANA as the strategic platform, organizations are now confronted with a compounded migration challenge:
- BDM is not natively supported on S/4HANA – it must be replaced.
- The successor solution, VSS by Pro Axia, runs as a certified S/4HANA add-on, delivering modern automotive DMS functionality aligned to SAP's clean core principles.
- Traditional migration approaches require multiple project phases – first migrating to S/4HANA, then re-implementing dealer functionality – creating cost overruns, extended timelines, and extended risk windows.
The Natuvion approach: One transformation, one step
The Natuvion Data Conversion Suite (DCS) is purpose-built for exactly this scenario. By combining deep SAP data model expertise with flexible transformation logic, DCS can simultaneously:
- Extract and migrate your core ECC business data to S/4HANA.
- Map and transform BDM-specific data objects – vehicles, service orders, warranty records, dealer hierarchies, and more – into the corresponding VSS data structures.
- Execute both workstreams within a single migration cycle, delivered through one integrated project.
The result is a dramatically simplified migration landscape: one project plan, one data migration run, one go-live event.
Why this matters for your program
-
Eliminates the need for a separate BDM retirement project.
-
Removes the risk of running a transitional S/4HANA environment without full dealer functionality.
-
Reduces total migration cost and elapsed timeline.
-
A single UAT cycle covering both core ECC and BDM/VSS data scenarios.
Full control over your data – leave it, transform it, or archive it
Not all data is equal. One of the most powerful aspects of the Natuvion approach is the flexibility it provides over what happens to your data during the migration:
Leave data behind
Historical data that is no longer operationally relevant – aged service records, superseded vehicle master data, or closed dealer accounts – can be selectively excluded from the migration. This keeps your new S/4HANA and VSS environment lean, performant, and free from legacy clutter, while reducing migration complexity and cost.
Transform data
Data that needs to move, but in a different shape, can be cleansed, enriched, and restructured on the way. The Natuvion DCS transformation framework supports complex mapping rules – including currency conversions, re-keying of material and dealer codes, restructuring of organizational hierarchies, and harmonization of customer and vendor master records to the new Business Partner model in S/4HANA.
Accelerate with Near Zero Downtime (NZDT)
For organizations where business continuity is paramount, Natuvion's Near Zero Downtime (NZDT) technology dramatically reduces the production cutover window. NZDT enables the bulk of data migration and transformation to occur while the source system remains live, with only a final delta synchronisation required at cutover. The outcome: a migration that fits inside a weekend window – or less – even for complex, high-volume environments.
Why Natuvion and VSS by Pro Axia?
The combination of Natuvion DCS and Pro Axia's VSS creates a uniquely powerful migration pathway for the automotive sector:
- Deep SAP data expertise: Natuvion has executed hundreds of SAP data migrations globally, with proven methodologies for complex carve-outs, system consolidations, and cross-release transformations.
- Certified S/4HANA tooling: The DCS is built specifically for SAP data migration – not a generic ETL tool retrofitted for SAP. It understands SAP's data dependencies, business object relationships, and technical constraints natively.
- Pre-built BDM-to-VSS content: Natuvion's transformation library includes pre-developed mapping and conversion content for BDM-to-VSS scenarios, significantly reducing project setup time and risk.
- NZDT for 24/7 operations: Automotive businesses often cannot afford extended system downtime. NZDT is specifically designed for high-availability production environments.
- End-to-end delivery capability: Through Natuvion’s global delivery network, we bring local expertise with global scale.
A migration program that fits your business
Every organization's data landscape is unique. Natuvion's toolset is designed to flex around your requirements – whether you are:
- A national automotive importer standardizing multiple dealer systems onto a single S/4HANA platform.
- A manufacturer subsidiary carving out from a global SAP environment.
- A dealer group moving from a regional ECC instance to a cloud-based S/4HANA PCE deployment.
Our approach starts with a structured discovery phase – using DCS Analyze to scan your existing BDM and ECC landscape, quantify data volumes, identify transformation complexity, and produce a reliable sizing and effort estimate. You get transparency before commitment.
