The Problem
Legacy BI migrations fail when teams treat them as simple "rebuild the reports" exercises. The real challenge is semantic: ensuring that every KPI, every filter, and every calculation produces the same result in the new platform. Without rigorous validation, you end up with two systems producing different numbers — and nobody trusts either one.
Use Case
SSRS, Cognos, Tableau, Qlik to PBI
Our Approach
We run a 4-phase migration: Discovery (inventory every report and data source), Design (map to Power BI semantic model), Build (implement with DAX + Star Schema), and Validate (automated numeric comparison between old and new). Every metric is verified to the decimal.
- Automated report inventory and usage analysis
- Semantic model design (Star Schema + Calculation Groups)
- Numeric validation framework (old vs. new comparison)
- User training and adoption support
Validation
Every metric verified to the decimal
Outcomes
- Full legacy decommission within 90-120 days
- Zero-discrepancy validation between old and new reports
- 40-60% license cost reduction from platform consolidation
Impact
Faster reports, lower costs
