Independent portfolio project — representative migration scenario, not a client engagement. No actual customer performance improvement is claimed; any future simulated benchmarks will be labelled as simulated.
Before: legacy environment
The representative starting point contains Excel files, SQL Server extracts, legacy Power BI datasets, duplicated reports, inconsistent KPIs, slow refreshes and loosely managed workspaces.
Audit: issues identified
Unclear source ownership
Duplicate logic
Competing definitions
Refresh risk
Role review needed
Workspace sprawl
Limited release controls
Usage to assess
Target Fabric architecture
Migration and validation
The representative plan sequences workload discovery, target design, proof of concept where needed, controlled migration, reconciliation against agreed source figures and release documentation. It prioritises reliability and traceability over a wholesale technical replacement.
Governance and performance
Workspace structure, access, deployment approach, ownership, documentation and lifecycle controls are designed alongside the technical work. Performance is measured against the actual environment; this case study deliberately does not invent a before/after benchmark.
