Migrating your Power BI Dataflows just became much easier. Microsoft has introduced the Dataflows Upgrade Wizard (Preview), a guided experience that helps eligible Fabric workspaces upgrade Dataflows Gen1 to Dataflows Gen2 while preserving key metadata and reducing migration complexity.

Here’s what you need to know:

Modernise When You’re Ready
You don’t need to upgrade your entire dataflow estate at once. The Upgrade Wizard provides a guided, self-service path to modernise selected Power BI Dataflows Gen1 while preserving your existing Power Query logic.
Unlock the Benefits of Dataflows Gen2
Fabric Dataflows Gen2 (CI/CD) builds on the familiar Power Query experience while adding capabilities for development, operations, integration, and scalability. With Git integration, Fabric deployment workflows, multiple data destinations, performance features such as Fast Copy and Partitioned Compute, and Copilot-assisted authoring, teams can build a more modern data workflow.
Upgrade with Confidence
The wizard assesses your dataflows before the upgrade and highlights whether they are Ready to migrate, Need Attention, or Upgrade unavailable. Once completed, the upgraded item preserves key elements such as its ID, schedule, queries, and connections, helping downstream reports and semantic models continue working without source remapping.
Validate and Move Forward
After upgrading, refresh your dataflows, rebind downstream dataflows, address any remaining recommendations, and update consumers using the legacy Power BI Dataflows connector. Because the upgrade cannot be reversed, start with a representative set of dataflows, validate the results, and expand your migration at a pace that works for your organisation.
