The BI Platform Migration Business Case
A CFO/CIO-ready framework for evaluating a move off Tableau, Qlik, Looker Studio, or a legacy BI platform - the real BI migration TCO model, the hidden costs vendors don't volunteer, and how to build a BI platform migration business case your board will actually approve.
Why BI Migrations Actually Get Approved
Almost no migration starts with "let's modernize our BI stack." It starts with one of these four pressures reaching a breaking point.
Licensing Cost Pressure
A renewal notice lands with a number Finance won't approve without an alternative on the table.
Tool Sprawl
Tableau in marketing, Qlik in finance, Looker Studio in product - nobody trusts the numbers.
Platform Consolidation
A Microsoft 365/Azure/Fabric investment already exists, and BI is the one workload still outside it.
End-of-Life or M&A
A platform is being sunset, or two companies merge with incompatible BI stacks overnight.
License Cost
The number every vendor leads with. Necessary, but rarely the deciding factor.
Migration Cost
Rebuilding dashboards, re-engineering data models, validating output.
Dual-Running Cost
Most enterprises pay for two licenses in parallel while trust is rebuilt.
How the Major BI Platforms Compare
Directional guidance for scoping conversations — always verify current list pricing directly with each vendor before budgeting.
| Platform | Relative License Cost | Positioning |
|---|---|---|
| Tableau | High | Standalone visualization leader; strong for complex, custom visuals |
| Qlik Sense | High | Associative engine; strong for exploratory, non-linear analysis |
| Looker Studio | Low / Free | Lightweight, Google-ecosystem native; scales poorly past departmental use |
| SAP Analytics Cloud | High | Deep SAP integration; being phased in favor of broader platform strategies |
| IBM Cognos | Moderate–High | Legacy enterprise reporting; common modernization candidate |
| Microsoft Power BI / Fabric | Low–Moderate | Native Microsoft 365/Azure integration; capacity-based scaling via Fabric |
