Switching Your BI Tool? Don’t Let Data Break the Story

Power BI. Tableau. Looker. Qlik.

Enterprises switch between them for better features, licensing needs, or strategy shifts. But there’s one thing that shouldn’t change—your data’s integrity.

At Vexdata, we help teams migrate from Tableau to Power BI, Qlik to Power BI, or even Power BI to Looker — without broken dashboards, inconsistent metrics, or analyst confusion.

Here’s how we make BI migration smoother, safer, and smarter.

🚨 The Real Risk Isn’t the Tool. It’s What Happens to the Data.

Migrating BI tools is not just a UI swap.

Each platform reads data differently:

Data types may be interpreted differently
Filters, joins, or calculated columns might behave differently
Underlying datasets may lose structure or granularity
Embedded logic might get lost or misaligned

If not validated correctly, dashboards look fine… until a stakeholder spots a sales figure off by 8%. That’s when the panic begins.

💡 Vexdata: Your Failsafe During BI Migrations

Here’s how we help ensure your reports stay accurate no matter which tool you move to.

✅ 1. Source-to-Target Validation at Every Layer

Whether you’re moving from Qlik to Power BI or Power BI to Looker, Vexdata checks:

Field-by-field accuracy between old and new datasets
Aggregates and totals across filters
Joins, filters, and calculated fields

What you see on one dashboard should match what you see on the other. We make sure it does.

🔁 2. Logic Translation Support

Each tool has its own syntax.

Vexdata helps identify gaps between:

Tableau’s calculated fields and Power BI’s DAX
Qlik’s associative logic and Power BI’s data model
Power BI’s relationships and Looker’s LookML

We help you validate logic equivalence, not just field names.

🧪 3. Automated Regression Testing

We support side-by-side testing of:

Top KPIs
Filters and slicers
Time comparisons
Drill-downs

You can catch inconsistencies before execs do.

📦 4. Validate Embedded and External Reports

Moving BI tools also means:

Embedded dashboards in apps must be verified
APIs or scheduled exports should match previous data

Vexdata runs validations against both, ensuring no silent failures.

📈 5. Analytics Confidence = Business Confidence

When migrations go wrong:

Sales teams lose trust in reports
Finance worries about reconciliation
CXOs doubt every number on a chart

When Vexdata validates the migration, you get clean, accurate dashboards from Day 1.
