Tableau to Power BI Migration,
Without the Rebuild
Structured · Validated · Low-Risk
Tableau licences keep climbing and the dashboards keep multiplying — so the move to Power BI keeps slipping to next quarter.
TabPower is Shvintech's Tableau to Power BI migration service. We assess your estate, convert dashboards and calculations to Power BI, and validate every report against the original before cutover — so your teams keep the insights they trust, without a manual rebuild.

What Our Tableau to Power BI Migration Covers
A structured migration from the first estate audit to the last validated dashboard — so nothing gets lost in the move.
Migration Assessment & Discovery
We inventory every workbook, dashboard, and data source and score each by complexity — so you get a clear scope, timeline, and cost before anything moves.
Dashboard & Workbook Conversion
Charts, filters, drill-throughs, and layouts are recreated in Power BI — so a migration that would take months of manual work lands far faster.
Calculated Fields & LOD → DAX
Tableau calculated fields, parameters, and Level-of-Detail expressions are translated into equivalent Power BI DAX — the part manual rebuilds get wrong most often.
Data Model & Semantic Layer
We rebuild your Tableau relationships as a governed Power BI semantic model, so business logic lives once and every report reads from the same source.
Validation & Parity Testing
Each migrated report is checked against its Tableau original — visuals, filters, and numbers — before sign-off, so users see what they trusted before.
Security, Governance & Adoption
Row-level security and permissions are recreated in Power BI, and your analysts get the enablement they need so adoption sticks after go-live.
As a leading software testing services company, we focus on reducing risk, improving release velocity, and ensuring consistent user experience.
A Structured 3-Step Migration
We analyse what you have, convert it accurately, and migrate only after every report is validated against the source.
Analyze
Assess your Tableau workbooks and data sources — identifying data connections, joins, worksheets, and any custom visuals that need special handling.
Convert
Translate Tableau calculated fields, LOD expressions, and parameters into Power BI DAX, and rebuild the semantic model and reports.
Migrate
Validate each report against its Tableau original, then cut over — running both platforms in parallel so there's no gap in reporting.
Migrate With Confidence.
Manual Rebuild vs. a Structured Migration
Most Tableau-to-Power-BI projects run into trouble for the same reason: they try to rebuild everything by hand.

Frequently Asked Questions
What teams ask most before starting a migration.
It depends on how many dashboards you have and how complex they are. We audit your estate first, so you get a firm timeline and scope before any commitment — not a guess.
Much of the conversion is tool-assisted — dashboards, calculated logic, and data models. Genuinely custom Tableau extensions are flagged during discovery and scoped separately, so there are no mid-project surprises.
Tableau's Level-of-Detail expressions don't map one-to-one to DAX, so they're translated by pattern: Fixed LODs to CALCULATE with explicit filters, Include LODs to iterator functions, and Exclude LODs to ALL/ALLEXCEPT. Every converted measure is validated against source output.
That's the point of parity testing. Each migrated report is checked against its Tableau original — chart types, filters, and calculated values — before sign-off, which is what protects user adoption.
No. Power BI is built alongside your live Tableau environment, and Tableau stays on until the new reports are validated and signed off — so there's no forced cutover and no gap in reporting.
The reasons that come up most are lower total cost, native integration with Microsoft 365 and Azure, and a path into Microsoft Fabric as analytics needs grow.
