KPMG replatforms Digital Gateway’s tax-data warehouse and analytics layer on Fabric

KPMG replatformed the Digital Gateway data warehouse and analytics layer on Microsoft Fabric, consolidating storage, compute, transformation, analytics and governance while continuing to interoperate with parts of the existing technology stack.

Organisation
KPMG Digital Gateway
Predecessor
Azure Synapse Analytics, Azure SQL, Azure Data Factory, Power BI, Excel, Alteryx and custom integrations
Destination
Microsoft Fabric data warehouse and analytics layer
Workload
KPMG Digital Gateway tax-data engineering, storage, analytics, reporting and governance
Stage
Operational production replatform; wider rollout continues
Retirement status
Fabric interoperates with the existing stack, so the source does not support retirement of every predecessor technology.
Confidence
High
Next trigger
A dated cutover, formal retirement statement or material later implementation milestone.
Evidence boundary: The evidence supports an operational replatform of Digital Gateway’s warehouse and analytics layer. It does not support a claim that every named predecessor tool was removed or that the wider rollout is complete.

Programme context

Implementation and architecture

  • Fabric provides a common storage, compute, transformation and analytics substrate.
  • Standardised pipelines and security policies support the global tax-data workload.
  • The source explicitly says Fabric interoperates with the existing stack; coexistence is retained as a boundary.

Known unknowns and contradictions

  • The exact production cutover date.
  • Which predecessor components were retired versus retained.
  • Completion timing for the continuing global rollout.

No missing fact is inferred to broaden the source-supported migration claim.

PlatformTrace analysis

The evidence supports an operational replatform of Digital Gateway’s warehouse and analytics layer. It does not support a claim that every named predecessor tool was removed or that the wider rollout is complete.

Performance, cost, uptime and operational outcomes remain attributed source claims unless independently stated otherwise.
