77 Tableau Reports Migrated to Power BI in 4.5 Months
BCT consolidated reporting on a Microsoft-aligned platform while preserving existing KPIs, calculations and functionality across four business functions.
Client
Challenge
The customer’s Tableau environment had grown complex across multiple business functions. Inconsistent business logic across dashboards created a risk of conflicting KPIs, while data-heavy reports experienced performance issues.
Every change in business requirements required updates across multiple dashboards, increasing manual maintenance and governance effort. Running a separate business intelligence platform alongside a largely Microsoft-based technology stack also added platform cost, licensing complexity and dependence on specialised Tableau skills.
The customer needed to standardise reporting on a platform that was easier to maintain, govern and use while preserving the business logic and expected results that teams relied on.

The customer needed to standardise reporting on a platform that was easier to maintain, govern and use while preserving the business logic and expected results that teams relied on.
Solution
BCT migrated the customer’s Tableau reports to Microsoft Power BI, creating a single reporting platform aligned with the existing Microsoft environment. Power BI provided native integration with the customer’s technology stack, a broader skills base and a self-service interface familiar to business users.
The migration was designed as a review, rebuild and validate process rather than a direct report conversion. BCT reviewed the business logic and KPIs in each report before rebuilding it, resolving inconsistencies instead of carrying them into the new platform.
Reports were recreated and simplified in Power BI while preserving expected calculations and functionality. Power Query, DAX and SQL supported data transformation and calculation conversion, while Power BI Service supported deployment and ongoing report management.
Experienced developers and testers with prior Tableau and Power BI migration experience identified dependencies and risks early. AI-assisted tools accelerated the translation of Tableau logic into Power BI and DAX, reducing manual conversion effort while structured validation maintained quality across the migration.

Impact
BCT delivered 77 Tableau reports on Power BI in 4.5 months. Existing KPIs, calculations and functionality were preserved, allowing business users to continue working with minimal disruption.
The migration standardised reporting across finance, commercial, product performance and supply chain functions. Resolving inconsistent logic during the rebuild created a more consistent basis for reporting and governance.
The customer reduced its ongoing dependence on Tableau-specific maintenance and moved to a simpler platform aligned with its Microsoft identity, security and licensing environment. The new foundation also provided a more accessible starting point for self-service reporting.
A repeatable review, rebuild and validation method, supported by AI-assisted conversion, established an approach that can be applied to future reporting migrations and platform modernisation initiatives.
