How to use this migration center¶

If you are an executive or decision-maker: Start with Why Power BI over Tableau and TCO Analysis. These two documents provide the strategic and financial case.

If you are a BI engineer or report developer: Start with Feature Mapping to understand the landscape, then jump to Calculation Conversion and Visualization Migration for the technical details. Use the Workbook to PBIX tutorial to do your first conversion end-to-end.

If you are a data engineer or platform team: Focus on Data Source Migration and Prep Migration for the data layer, then Server Migration for infrastructure.

If you are running the migration program: Read the full Migration Playbook first, then use this center as a reference library for each phase.
