A growing fleet does not stay understandable on a pile of Tableau workbooks. Fleet performance, driver activity, and revenue each grew their own reports. The transportation company in this Tableau to Power BI case study needed one governed place to run the operation.
The customer is a fleet operator modernizing operations through driver support and data-driven reporting. Revenue across multiple transportation revenue channels had made the Tableau estate hard to inventory and harder to change.
They engaged BIChart for a Tableau migration assessment and the migration engine, and paired that with their system integrator. The work was to inventory Tableau, convert priority fleet, driver, and revenue workbooks to Power BI, and land the migration in Microsoft Fabric.

Starting Point: Reports Had Outgrown the Operation
The estate was large enough that a manual rebuild would have burned the integrator on conversion instead of rollout:
- 100+ reports
- 10+ published data sources
- Priority workbooks covering fleet performance, driver activity, and revenue
The first job was not a new chart style. It was to see what existed, what people still used, and what could be archived before anything moved.
Tableau to Power BI Case Study: What They Asked BIChart to Do
- Inventory Tableau and decide what to keep, convert, or retire
- Convert priority fleet, driver, and revenue workbooks to Power BI
- Carry the migration from Tableau onto Microsoft Fabric
Their data and analytics leader described the working model:
We engaged BIChart early in our process to inventory our reports and dashboard utilization. BIChart was easy to work with to deliver a suite of tools to our system integration team so we could reduce the overall level of effort.

What the Tableau to Power BI Migration Delivered
Assess the Tableau environment. BIChart evaluated the existing estate so the team could tighten governance and set a base for reporting that can scale.
Lift and shift Tableau to Power BI and Fabric. Conversion took expression and connection work off the system integrator. That team spent the recovered time on rollout and adoption.
The delivery included:
- A full inventory and de-duplication of workbooks and data sources
- Tableau direct queries mapped to canonical SQL
- Automated conversion of Tableau reports and connections to Fabric and Power BI
Outcomes
- A clear plan for what to archive in Tableau and what to migrate
- Faster time to value on the priority fleet, driver, and revenue reports
- A toolset the existing system integrator could run without a separate conversion project
Plan the Same Path
If you need the inventory before you commit to a rebuild, start with a BIChart assessment. It shows which Tableau assets still matter, then the same engine can move the priority workbooks to Power BI and Fabric.
