SAP Greenfield Migration: Workflow and Evidence Guide

Decision context

SAP greenfield migration involves implementing a new SAP system landscape from scratch, often to adopt S/4HANA with clean core principles. This approach requires extensive planning, code and data redesign, and rigorous change governance to avoid legacy complexity and ensure future extensibility.

Adranum supports greenfield migration by ingesting diverse SAP evidence such as ABAP code readiness, data quality, process events, and requirements. It maps dependencies and supports decisions to keep, replace, remediate, or retire objects, ensuring that migration proposals are reviewable and traceable.

The platform’s governance capabilities include generating implementation packages, coordinating cutover and reconciliation, and recording human approvals. Adranum’s architecture allows customers to retain sensitive data and credentials in-house while receiving bounded commands and aggregate outcomes, enabling secure and compliant migration workflows.

Understanding SAP Greenfield Migration Challenges

Greenfield migration is a complex endeavor that demands starting with a clean SAP system, often to leverage S/4HANA’s innovations without legacy constraints. It requires comprehensive assessment of existing custom code, data models, and processes to determine what to build anew versus what to migrate or retire.

Key challenges include managing dependencies across ABAP objects, ensuring data quality, and coordinating multiple change streams involving code, configuration, and testing. Without proper governance, risks of incomplete coverage, unsupported inputs, or inconsistent approvals increase, potentially causing project delays or quality issues.

• Extensive custom code and data redesign
• Dependency mapping for ABAP and DDIC objects
• Coordinated cutover and reconciliation management

Adranum’s Role in Greenfield Migration Governance

Adranum ingests authorized SAP readiness and code quality evidence, including ATC and abapGit results, to provide a unified view of migration scope and status. It highlights unsupported inputs and gaps in coverage to guide focused remediation.

The software supports decision-making by mapping observed and inferred dependencies, enabling keep/replace/remediate/retire choices with traceable justifications. Generated code and data proposals remain reviewable until customer-controlled compilation and runtime validations succeed.

Human approvals are recorded systematically, and implementation packages are content-addressed for integrity. Coordination of cutover, reconciliation, continuity, and exact-state recovery ensures operational continuity during migration phases.

• Unified ingestion of SAP readiness and quality evidence
• Dependency mapping with decision support
• Reviewable code and data proposals with approval tracking

Integration with Customer Infrastructure and Security

Adranum’s design enables customers to keep raw service data, source code, and credentials within their own infrastructure, mitigating security and compliance concerns. Only bounded commands, hashes, aggregate outcomes, and reconciliation evidence are transmitted externally.

This architecture supports strict data governance policies common in SAP landscapes undergoing transformation. It also facilitates auditability by preserving detailed compile, runtime, test receipts, and reconciliation artifacts within the customer environment.

By minimizing external data exposure, Adranum helps organizations maintain control over sensitive SAP assets while benefiting from automated governance and coordination features.

• Customer-controlled data and credential retention
• Transmission limited to bounded commands and aggregate outcomes
• Comprehensive audit and reconciliation artifact preservation

Process Variant and Bottleneck Analysis for Continuous Improvement

Adranum captures observed process variants and bottlenecks during migration simulations, enabling teams to identify inefficiencies and areas for optimization before production rollout.

Immutable simulations allow replaying migration scenarios to validate decisions and track improvement history, supporting iterative refinement of migration plans.

These capabilities help reduce risks associated with greenfield migration by providing actionable insights into process performance and change impact.

• Observed process variant tracking
• Bottleneck identification and analysis
• Immutable migration scenario simulations

Limitations and Considerations for SAP Greenfield Migration

Adranum does not replace SAP licensing, Basis administration, or specialist testing tools required for comprehensive migration validation. Generated code proposals require customer compilation and runtime checks to confirm correctness.

The software does not provide official SAP certification or guarantee cost savings or ROI. Missing or incomplete inputs remain visible and must be addressed by the customer.

Adranum is not a substitute for accountable architects or production ownership; it complements governance by providing evidence-based coordination and decision support.

• Not a replacement for SAP licensing or Basis administration
• Generated code proposals require customer validation
• No official SAP certification or guaranteed savings

What the workflow must cover

• Evidence Ingestion and Coverage Reporting. Adranum collects authorized SAP readiness, ATC, ABAP, DDIC, and data quality evidence to provide comprehensive coverage reports and highlight unsupported inputs.
• Dependency Mapping and Decision Support. The platform maps observed and inferred dependencies among SAP objects, supporting keep, replace, remediate, or retire decisions with traceable justifications.
• Reviewable Code and Data Proposals. Generated code and data change proposals remain reviewable until customer-controlled compilation and runtime validations succeed, ensuring quality control.
• Implementation Package Generation. Adranum creates content-addressed implementation packages and impacted test sets, facilitating structured deployment and validation workflows.
• Approval Recording and Coordination. Human approvals are systematically recorded, and cutover, reconciliation, continuity, and exact-state recovery are coordinated to maintain operational integrity.
• Process Variant and Bottleneck Analysis. The software captures observed process variants and bottlenecks during simulations, enabling continuous improvement and risk mitigation.

Implementation workflow

Start with a bounded customer scenario and explicit acceptance criteria. Preserve native SAP permissions and accountable review while the software creates a repeatable evidence chain.

1. Collect authorized SAP readiness and quality evidence including ATC, abapGit, and data quality reports.
2. Ingest and analyze evidence to map dependencies and identify unsupported inputs or gaps.
3. Support keep/replace/remediate/retire decisions with traceable justifications and generate reviewable code and data proposals.
4. Record human approvals for proposed changes and generate content-addressed implementation packages.
5. Coordinate cutover, reconciliation, continuity, and exact-state recovery activities with audit trail preservation.
6. Perform immutable simulations to identify process variants and bottlenecks and refine migration plans.
7. Maintain comprehensive evidence and receipts within customer infrastructure for compliance and auditability.

Evidence to require

A transformation claim should resolve to observable artifacts, decisions, and execution receipts. Ask for the following evidence in a representative evaluation:

• SAP ATC (ABAP Test Cockpit) reports
• abapGit source control snapshots
• Data dictionary (DDIC) metadata
• Process event logs and variants
• Requirement traceability matrices
• Data quality assessment reports
• Connector configuration and status
• Compilation and runtime test receipts
• Human approval records
• Reconciliation and cutover logs

Boundaries and non-claims

Adranum separates analysis, proposal, human review, package creation, customer-local validation, and production execution. A later state never rewrites the evidence that supported an earlier decision.

• Adranum does not replace SAP licensing or Basis administration responsibilities.
• Generated code proposals require customer compilation and runtime validation before production use.
• The platform does not provide official SAP certification or guarantees related to cost savings or ROI.
• Missing inputs and unsupported evidence remain visible and must be addressed by customers.
