Key takeaways
- Power BI Premium capacities have moved to Microsoft Fabric, so most organisations migrate from Premium (P) to Fabric (F) capacity.
- A good migration is phased: assess, size a Fabric capacity, move workspaces, modernise the model, validate, then optimise.
- Direct Lake and OneLake are the big wins — faster reporting on one governed copy of your data.
- Migrate on a plan, not in a panic. Validate every key number against the original before you switch off the old setup.
If you run Power BI at any scale, a move to Microsoft Fabric is now a question of when, not if. Microsoft has folded Power BI Premium into Fabric, and the platform unlocks faster reporting and a single home for your data. This is a practical, step-by-step guide to migrating from Power BI to Microsoft Fabric — and how to do it without breaking the numbers your team relies on.
Why migrate from Power BI to Fabric?
Three reasons come up again and again:
- Premium is now Fabric. Power BI Premium capacities have transitioned to Fabric capacities, so many teams are moving as a matter of course.
- One copy of your data. OneLake gives you a single governed store that every workload reads — no more copying data between tools.
- Faster reporting. Direct Lake lets Power BI read straight from OneLake, giving import-level speed without refreshes.

What actually changes
For most existing reports, less than you might fear. Your Power BI reports and datasets keep working; what changes is the capacity they run on and, over time, where the data lives. The migration is mostly about the platform underneath — capacity, OneLake and the model — not rebuilding every report.
A step-by-step migration
Step 1 — Assess your estate
Inventory your workspaces, datasets, capacities and refresh loads. Identify the heavy models, the critical reports, and anything already fragile. You cannot plan a move you have not measured.
Step 2 — Size your Fabric capacity
Choose a Fabric capacity (an F SKU) sized to your workload, replacing your Premium (P) capacity. Right-sizing here controls cost, so base it on real usage, not guesswork.
Step 3 — Enable Fabric and prepare OneLake
Turn on Fabric, create your workspaces on the new capacity, and set up OneLake as the home for your data.
Step 4 — Move workspaces and content
Reassign Power BI workspaces to the Fabric capacity. In many cases this is an in-place change, and existing reports keep running while you modernise behind them.
Step 5 — Modernise the model
Bring data into OneLake using a lakehouse or warehouse, and adopt Direct Lake for large models so reports read straight from the lake — the step that delivers the performance gains.
Step 6 — Validate the numbers
Reconcile every key figure against the original, test refresh and performance, and confirm row-level security still behaves. This validation is what earns the trust to switch over.
Step 7 — Optimise and govern
Right-size the capacity, set up governance and monitoring, and document the new setup so the platform is maintainable.
How to de-risk the move
Migrate in phases, never big-bang. Keep the old setup live until the new one is validated. Protect row-level security and access rules exactly as they were. And treat the semantic model as the asset it is — a clean, governed model is what makes Fabric fast and trustworthy.
What this means for UAE teams
For businesses in Dubai and the UAE already on Microsoft 365 and Azure, migrating to Fabric consolidates the data stack and future-proofs reporting. The teams that migrate smoothly are the ones that plan, validate and bring the right skills — whether in-house or with a partner.
Migrate to Microsoft Fabric with confidence
Gulf BI Analytics runs Power BI to Microsoft Fabric migrations for UAE teams — assessed, phased and validated, with governance kept intact.
