SAP S/4 Migration
S/4 projects collapse when access, roles and licensing are left untouched. Clean authorisations, risk-aligned roles and transparent usage make testing smoother, cutovers predictable and go-lives stable.
Your shift from ECC to S/4 becomes stronger when the foundation is rebuilt to support it.
WHY S/4 MIGRATION NEEDS ACCESS EXPERTISE
Roles Decide Whether the Migration Breaks or Holds.
Most S/4 delays start with access. Roles that do not match processes. SoD rules that stop approvals. Licensing that explodes during prep. When access, controls and usage do not align early, every migration phase slows down and risk increases.
A stable S/4 requires a stable access model underneath it.
Roles Built for an S/4 Cutover
ECC roles rarely fit S/4. Authorisations are rebuilt to match S/4 structure and security requirements.
Testing That Moves Without Blockers
Aligned access prevents rework. Authorisation issues do not stall test cases, UAT or cutover steps.
Licensing That Matches Real Usage
Users are classified by behaviour, not titles. S/4 licensing becomes predictable instead of reactive.
Access That Follows Real Processes
Permissions reflect how your organisation works so automation, approvals and audit trails stay intact after go-live.

RISK AND COMPLIANCE
Compliance That Moves With the Migration.
S/4 is the moment to fix what ECC allowed to drift. Compliance, SoD, transports, licensing and identity must be part of the new structure, not retrofitted later.
Controls stay consistent from ECC through cutover and into the new S/4 environment.
