Data Migration
Move to Power BI Without Losing Your Reports
Allston Yale runs Tableau to Power BI migrations for mid-market companies in Texas and across the USA. When a renewal looms or leadership decides to consolidate on Microsoft, we move you across without the project becoming its own disaster.
01
The Fear in Every Migration
The fear is always the same: that reports will break, dashboards will vanish, and the numbers will stop matching. Our whole method is built to take that fear off the table, so the switch feels like an upgrade rather than a leap.
02
Why Teams Move From Tableau to Power BI
The trigger is usually money. Tableau licensing adds up, and teams already paying for Microsoft 365 find Power BI far cheaper to run for the same reporting. Consolidating on one vendor also means one less tool to license, learn, and support.
The deeper reason is the stack. With Power BI sitting inside Microsoft Fabric, your reporting and your data platform finally live together, which is hard to match while your dashboards sit in a separate tool from everything else you run.
03
How We Run a Tableau to Power BI Migration
We do not lift and shift blindly. First we inventory every Tableau workbook and find out which ones people actually use, because a third of them usually go untouched. That alone shrinks the job and the eventual licensing footprint.
Then we rebuild the reports that matter on a clean Power BI model, run the old and new side by side so you can compare, and cut over only once the numbers reconcile. The conversion is deliberate, not a risky overnight swap.
04
Keeping the Numbers You Trust
This is the part that makes or breaks a migration. For every report we move, we reconcile the Power BI output against Tableau line by line until the totals agree, so no one opens the new dashboard and quietly loses faith on day one.
05
Migrating From Other Platforms Too
Tableau is the most common move, but not the only one. We also migrate from Cognos, QlikView and Qlik Sense, SSRS, SAP BusinessObjects, and MicroStrategy, each in its own guide [links]. The method is the same: keep what is used, rebuild it clean, prove the numbers.
06
A Migration Is a Chance to Fix, Not Just Copy
Copying a messy Tableau estate into Power BI just moves the mess. A migration is the rare moment everyone agrees to clean house, so we use it to retire dead reports, fix broken calculations, and leave you with fewer dashboards that each earn their place.
07
Built on Power BI and Microsoft Fabric
Your reports land in Power BI, and the data feeding them lands in Microsoft Fabric. For the reporting craft itself see our Power BI consultant page, and for the platform underneath see our Microsoft Fabric consulting page.
08
Industry Experience
We migrate for the industries that drive the Texas economy and beyond: oil and gas, energy and utilities, manufacturing, healthcare, banking and insurance, and construction. Each has reports that cannot afford to go wrong during a move, from production to claims.
That context lowers the risk. We know which numbers your sector watches most closely, so those get reconciled first and tested hardest before anyone is asked to rely on the new version.
What working with Us Looks like
Clients come to us dreading the migration and are often surprised by how calm it stays. The goal is a move the rest of the business barely feels, where the reports simply reappear in a new place, still correct and still trusted.

Common Questions
How long does a Tableau to Power BI migration take?
It depends on how many reports survive the cull, not how many you have today. A focused first wave of the reports that matter usually lands in weeks, with the rest phased so the business is never waiting on a single big switch-over.
Will the reports look the same in Power BI?
Close, and often better. Power BI and Tableau do similar things differently, so we match the intent of each report rather than copying it pixel for pixel. Where a Tableau habit does not translate, we rebuild it the way Power BI does best.
What happens to Tableau-specific features?
Most have a Power BI equivalent, from level-of-detail calculations to parameters and actions. We map each one during the audit and flag anything genuinely unique early, so there are no surprises halfway through the conversion.
Can we run Tableau and Power BI at the same time?
Yes, and we recommend it. Running both in parallel for a short window lets people compare the new reports against the old and build trust before you drop the Tableau licenses. The overlap is brief and well worth the confidence it buys.
