Qlik. Looker. Sigma. ThoughtSpot. Metabase. Superset. Whatever platform you're evaluating, or whatever combination of platforms your team can't agree on yet, the conversation usually starts with a feature comparison and ends with the same unanswered question: what's actually in our Tableau environment right now?
Most teams past a few hundred workbooks can't answer that with confidence. Not because nobody's tried, but because the answer lives in hundreds of individual workbooks, in calculated fields and LOD expressions nobody wrote documentation for, in data source connections nobody's audited in years.

The part every path shares
Every migration path, regardless of destination, requires the same groundwork: rationalization, semantics, context, and structural analysis. The platform comparison matters. It's just not the first decision. The first decision is understanding what you have, because that's what determines whether any destination is realistic, what it'll actually cost, and what you'd be leaving behind.
What has to happen before anything moves
- Inventory what's actually in use. Usage data, not assumptions, should decide what gets migrated.
- Extract the business logic. Calculated fields and LOD expressions encode business decisions that exist nowhere else. Losing them in a rebuild means re-deriving logic your organization already solved once.
- Map data source dependencies. Know what each workbook depends on before any platform evaluation gets specific.
- Score what's worth rebuilding. Some workbooks justify the migration effort. A lot of them don't, and shouldn't make the trip.
Where BIChart fits
BIChart's Tableau Assessment builds that inventory first, against metadata only, without touching production. It surfaces workbook health, usage, data source dependencies, and the business logic inside calculated fields, before you've committed to a destination platform.
To be direct about scope: BIChart's automated migration engine converts into Power BI and Microsoft Fabric. For any other destination, the assessment still does the part that matters most, giving your team an accurate, defensible picture of the environment you're migrating out of.
Start with the assessment. Request assessment access before the platform debate goes any further.
