Tableau to Power BI Migration

No - and be cautious of anyone who promises otherwise. There is no reliable one-click conversion between Tableau and Power BI, because the two platforms calculate and render fundamentally differently. LOD expressions, table calculations, parameters and dashboard actions all need deliberate re-engineering as DAX measures on a properly structured data model. What makes migration efficient isn't automation - it's method:

• Triage first: retiring unused workbooks before anything is rebuilt.

• Pattern library: solving each conversion challenge once, then reusing the pattern across every wave.

• Reconciliation: validating every converted number against the Tableau original.

Rebuilt properly, your Power BI reports usually end up faster and cleaner than the workbooks they replace.

Migration costs depend almost entirely on how many workbooks survive triage - small estates often migrate for $10,000 to $25,000, while larger multi-department estates typically range from $30,000 to $80,000+. The fixed-fee assessment and roadmap starts from $5,000 and pays for itself by cutting scope: in most estates a meaningful share of workbooks are duplicated, superseded or simply unused, and retiring them is free. The licensing comparison we produce usually shows the project recovering its cost within the first one to two renewal cycles.

Most migrations complete within 6 to 16 weeks, driven by workbook count, calculation complexity and how quickly business owners can validate each wave. Typical shape:

• Assessment & triage (1-2 weeks): inventory, usage analysis, roadmap and licensing comparison.

• Pilot conversion (2-3 weeks): priority dashboards rebuilt, patterns and templates established.

• Migration waves (3-10 weeks): remaining workbooks converted, validated and signed off in batches.

• Parallel run & switch-off (2-4 weeks): training, adoption monitoring and Tableau decommissioning.

We time the cutover against your Tableau renewal date, so you never pay for both platforms longer than necessary.

For most organisations, yes - per-user Power BI licensing typically costs a fraction of equivalent Tableau Creator and Explorer seats, and many businesses already hold Power BI entitlements through their Microsoft 365 agreements. The real comparison depends on your mix of report builders versus viewers, and whether you need Premium Per User features or dedicated Fabric capacity. That is exactly what our licensing model quantifies: your current Tableau spend, the matching Power BI configuration, and the annual difference. For Microsoft-aligned organisations the consolidation case is usually compelling - one vendor, one security model, and reporting that lives natively in Teams and Excel.

We'll show you the genuine numbers for your user base before you commit - including if the answer is that staying on Tableau makes more sense for you.

Your dashboards will answer the same questions with the same numbers, but Power BI is not a pixel-for-pixel clone of Tableau - and treating it as one produces slow, awkward reports. Our approach is design parity, not replication: we preserve the KPIs, layouts, drill paths and filters your users rely on, while adapting to Power BI's strengths and conventions.

• What stays the same: metrics, business logic, drill-downs, security access and the answers users come for.

• What improves: load times, mobile and Teams access, and the clutter that accumulated over years of patching.

• What changes: some interactions work differently, which is why every wave includes user walkthroughs and training.

Every rebuilt dashboard is signed off by its business owner against the Tableau original before the old version is retired.
