Enterprise Data Migrations at Scale
Multi-Cloud Data Migration for a Professional Body (Accenture UK)
Salesforce, Zuora, Commercetools | Multi-country | 57M+ records
Context
A professional membership organisation was replacing multiple legacy systems with a new multi-cloud digital platform. The programme operated under regulatory scrutiny and a fixed 10-day cutover window, with fragmented legacy data across customer, membership, payments, and product domains.
Problem
Legacy data structures were inconsistent and misaligned across systems, while the cutover window allowed no recovery time. Data quality, reconciliation, and executive confidence all needed to be addressed upfront.
Delivery
- Led the end-to-end data migration delivery, owning migration architecture, cutover planning, and execution governance.
- Designed metadata-driven migration pipelines and canonical data structures to harmonise fragmented source systems.
- Directed a 15-person team across architecture, engineering, and validation, enforcing readiness criteria and reconciliation controls.
Outcome
- Successful migration of 57M+ records within the immovable cutover window.
- Real-time reporting on migration status, progress, and data quality, enabling informed executive decision-making throughout cutover.
- Clean, auditable data loads across all target platforms with zero critical defects at go-live.

Data Governance, Readiness, and Audit Assurance
Planned Data Governance and Readiness Across ERP and HCM Programmes (Accenture UK)
Oracle Cloud ERP/HCM | Workday | Regulated environments
Context
Multiple ERP and HCM programmes required data to be production-ready at go-live for payroll, finance, reporting, and audit purposes. From programme initiation, data readiness and auditability were treated as delivery-critical requirements.

- Faster and more confident sign-off driven by visible evidence of data readiness.
- Data trusted from day one for operational use, reporting, and regulatory scrutiny.
