They should test whether access approvals, entitlement reviews, and audit logs are still produced without modifying the core application. If evidence requires manual reconstruction or one-off code, governance is not operationally stable. The right signal is repeatable control evidence generated through supported interfaces across release cycles.
Why This Matters for Security Teams
Migration is where SAP governance often looks healthy on paper but weak in operation. Compliance teams are not really asking whether the app still runs; they are asking whether access approvals, entitlement reviews, and audit evidence still happen through supported controls after the cutover. If the answer depends on spreadsheets, manual screenshots, or custom code, the control may be visible to auditors but not dependable in production. That distinction matters because governance must survive release cycles, not just implementation projects.
This is especially important in SAP environments where privilege, business process, and auditability are tightly coupled. A migration can change the identity model, workflow engine, or logging path without changing the apparent user experience, which is why control testing has to be evidence-based. The question is less about configuration and more about repeatability: can the team still prove who approved what, who reviewed access, and what the system recorded, without rebuilding the record by hand? Current guidance from NIST Cybersecurity Framework 2.0 and NHIMG’s Ultimate Guide to NHIs — Regulatory and Audit Perspectives both point toward repeatable, auditable control operation rather than one-time evidence collection. In practice, many security teams discover broken governance only after an audit request forces manual reconstruction, rather than through intentional control testing.
How It Works in Practice
Testing SAP governance after migration starts with three checks: approvals, entitlement reviews, and logs. First, confirm that access requests still route through the supported approval path and retain approver identity, timestamp, and outcome. Second, verify that periodic access recertification still produces a complete review trail, including exceptions and remediation actions. Third, validate that audit logs remain searchable, tamper resistant where required, and tied to the same identity objects used by the migrated system. The key is to test evidence generation end to end, not only interface availability.
A practical control test usually includes a sample of real transactions, a review of the data fields in the exported evidence, and a comparison of pre-migration versus post-migration outputs. If the new environment emits different IDs, renamed roles, or changed timestamps, the team needs documented mappings so auditors can trace continuity. NHIMG’s Top 10 NHI Issues highlights a broader lesson that also applies here: governance breaks when credential, logging, or review processes lose operational visibility. For control design and evidence expectations, NIST Cybersecurity Framework 2.0 is a useful anchor because it emphasises repeatable protective and detective outcomes, not just policy statements.
- Run the same approval and review workflow before and after migration.
- Check whether logs are produced by the supported platform interfaces, not ad hoc exports.
- Confirm that entitlement data is still authoritative and reconciled to the target system.
- Document any mapping needed to translate legacy IDs, roles, or audit fields.
Where teams need a deeper operating model, NHIMG’s Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs is useful because migration should preserve identity lifecycle control, not weaken it. These controls tend to break down when SAP is heavily customised, because evidence paths become dependent on bespoke code, brittle integrations, or manual reconciliation jobs.
Common Variations and Edge Cases
Tighter governance testing often increases operational overhead, so teams have to balance audit confidence against migration speed. That tradeoff is real, especially when SAP is integrated with multiple upstream identity sources or downstream reporting tools. There is no universal standard for every landscape, but current guidance suggests that if the control evidence is not generated by the system of record, it should be treated as fragile and revalidated after each change.
One common edge case is hybrid operation, where part of the workflow remains in the legacy stack while approvals or logs move to a new platform. Another is delegated administration, where business owners can approve access but cannot produce a clean review trail after migration. A third is role redesign, where the team replaces old technical roles with new business roles and loses traceability between the two. In all of these cases, the migration may be technically successful while governance is still partially manual. That is why compliance teams should test for continuity of control evidence, not just continuity of application access.
For risk framing, the same principle used in NIST Cybersecurity Framework 2.0 applies here: evidence must be reliable enough to support decisions. If a migration forces one-off scripts, human reconstruction, or unapproved report generators, the governance model is no longer stable enough for sustained audit reliance.
