Power BI Premium to Fabric Migration

Microsoft Fabric adds the components that Power BI Premium was missing. These include Spark for engineering, real-time pipelines, and full lakehouse architecture. Power BI Premium per capacity SKUs are being phased out. Moving to Fabric (F-SKUs) capacity is now mandatory for companies using Power BI Premium capacity.

Microsoft Fabric Features & Benefits

1. Technical Consolidation

Microsoft Fabric unites different Microsoft data tools into one. It combines data engineering with Spark notebooks, data warehousing with T-SQL, data integration with Data Factory, and more. Microsoft Fabric combines storage, processing, data analysis, and business analysis into one place.

Before Microsoft Fabric, most companies relied on separate tools for different data tasks like Azure Data Factory, Azure Synapse, and Power BI. Now, everyone (data engineers, data scientists, database administrators, and business intelligence developers and analysts) works with the same data in OneLake, using open Delta Parquet files. When all teams use the same system, they no longer need to connect different tools or move data back and forth.

2. Performance

Power BI, previously designed just for dashboards and visuals, can now connect directly to lakehouses and Delta tables (rather than connecting to Spark notebooks), which makes data models faster using Direct Lake mode.

For example, if a data engineer applies optimizations to a Delta table (for example, V-Order compression, Z-Order, or Liquid Clustering), it can make Power BI's Direct Lake query speeds 3 to 5 times faster while reducing compute costs.

3. Security & Governance

Microsoft Purview is built into Fabric. It automatically tracks where data came from and what has been done to it. You can also set sensitivity labels to prevent sensitive data from being shared or exported by accident. Data owners set who can view what in OneLake. They only need to do this once.

Microsoft Fabric makes managing data security and compliance simpler by putting everything in one place. All data processing uses the same storage layer (OneLake), where rules are already in place. When anyone then uses Spark, SQL, or Power BI, the security rules automatically apply and are enforced. When a user runs a SQL query or a Power BI report, the rules are checked and enforced on the spot.

Microsoft Fabric is very flexible for designing a data environment. But you have to set up everything securely right from the start. Otherwise, there is a risk that your sensitive data could end up exposed. Proper architecture from the outset means your platform can stay compliant and scalable as your business grows.

For regulated industries like healthcare and fintech, experienced data architects or BI consultants with domain knowledge can help you integrate Fabric with Microsoft Purview to meet strict compliance rules. They know how to set Data Loss Prevention policies, which automatically block access to sensitive information, and set up OneLake security for role-based, centralized access control. Expert guidance in deploying Insider Risk Management can help you spot risky data activity.

4. Cost Efficiency

Microsoft Fabric has a different billing system than Power BI Premium. Instead of buying a traditional capacity license, your company pays for the Capacity Units and F-SKUs you use. You have the option of paying upfront for one or three years or paying as you go, paying only when the system is actively used.

If you consistently exceed your capacity limits, the system slows everything down (throttling). Fabric Capacity Overage lets you pay for the extra capacity automatically when you go over your limits, without slowing down. You can also turn off development and test environments outside working hours to save money.

5. Operational Visibility

Microsoft Fabric offers tools that let DataOps teams monitor all data pipelines from one dashboard. The Capacity Metrics App shows who is using what and which workloads are using the most resources, so you know when it is time to upgrade, autoscale, or identify poorly optimized queries. Developers can schedule when their data is refreshed and when large Spark jobs run to spread out the workload. They see when something is not working as expected and can fix it before it affects the rest of the company. You can monitor your usage and adjust it accordingly.

To keep everything running smoothly, best practices suggest creating a Microsoft Fabric Center of Excellence. This team sets standards, manages server and compute resources, and trains staff members.

Common Migration Challenges and Pitfalls

Moving from Power BI Premium to Fabric isn’t always smooth. There are plenty of traps teams fall into early on. Knowing what can go wrong helps you plan around it and avoid wasting time (or budget) fixing preventable problems.

Fabric introduces new tools, new architecture, and a different pricing model. That means new skills, planning effort, and real risk if teams go in blind. The pain comes when companies skip the preparation stage.

Tooling Complexity & Skill Gaps

One of the big hurdles with Fabric is the skill gap. It casts a wide net: no single person or team is likely to have it all from the start.

You might have great Power BI and DAX folks, but little to no experience with Spark or Python. That slows things down and leads to underused features.

Mastering Fabric requires expertise across a wide range of tools spanning data engineering, analytics, and BI.

Without serious upskilling, teams risk falling back on old habits, like using the wrong tools for the job or missing what Fabric can actually do.

Steep Learning Curve & Lack of Best Practices

Fabric is still new, and the playbook is not fully written yet. Microsoft offers docs and templates (mostly lifted from Synapse and Data Factory) but there is no built-in framework for how to actually structure your projects. You are starting with a blank slate.

That freedom can backfire if teams wing it without clear guidance. Without predefined standards, organizations have to create their own rules: workspace setup, naming conventions, data lake zones, all of it.

And until that settles, most teams go through a trial-and-error phase that slows things down.

Fragmented or Redundant Solutions

Fabric gives you a few different ways to do the same thing, like loading data through Pipelines, Dataflows, or notebooks. That sounds flexible, but it often leads to confusion. Teams start using different tools for the same job, without talking to each other. That is how you end up with duplicate workflows and zero visibility. Unless you set clear rules on what to use and when, things drift fast.

Capacity and Licensing Surprises

Fabric doesn’t use fixed capacity like Power BI Premium. It runs on compute units: scale up, down, pause. You pay for usage.

Sounds fine. Until you get the bill.

Teams pick F32 to save money. But anything below F64 drops free viewing. Now every report needs a Pro license. Under Premium? Included. Under Fabric? Extra cost. And most teams don’t see it coming.

Plenty of companies that switched to F32 thinking they were optimizing costs got hit later with Pro license expenses.

Want the same viewer access as P1? You’ll need at least F64. That can cost 25–70% more, depending on setup.

There are ways to manage it (annual reservations, Azure commit discounts) but only if you plan before migration. Not after.

Data Refresh and Downtime Considerations

The mechanics of migrating workspaces are straightforward (reassigning workspaces to the new capacity), but there are operational gotchas. When you migrate a workspace, any active refresh or query jobs are canceled and must be rerun, and scheduled jobs resume only after migration. If not carefully timed, this could disrupt data refresh schedules. Customers may need to “recreate scheduled jobs” or at least verify them post-migration to ensure continuity. Planning a hybrid migration (running old and new in parallel) can mitigate disruptions.

Rely on Belitsoft technology experts to use their in-depth knowledge, broad expertise, and strategic thinking to assist you in legacy migration to Microsoft Fabric, while minimizing downtime and ensuring continuity.

Resource Management Pitfalls

Fabric lets you pause or scale capacity. Sounds like a good way to save money. But when a capacity is paused, nothing runs — not even imported datasets. Reports go dark.

Companies with global teams or 24/7 access needs quickly learn: pausing overnight isn’t an option.

There’s another catch: all workloads share the same compute pool. So if a heavy Spark job or dataflow kicks off, it can choke your BI reports unless you plan around it.

Premium users didn’t have to think about this: those systems were separate. Now it’s on you to tune compute (CUs), schedule jobs smartly, and monitor usage in real time.

Ignore that, and you’ll hit capacity walls: slow reports, failed jobs, or both.

Pricing and Licensing Differences

One of the biggest changes in moving to Fabric is the pricing and licensing model. Below is a comparison of key differences between Power BI Premium (per capacity) and Microsoft Fabric.

Key takeaways on pricing/licensing

Existing Power BI Premium customers will need to transition to an F SKU at their renewal (unless on a special agreement). In doing so, they should prepare for potential cost increases at equivalent capacity levels, although Fabric’s flexibility (smaller SKUs or scaling down) can offset some costs if used wisely.

The benefits of Fabric’s model include more granular scaling, alignment with Azure billing (useful if you have Azure credits), and access to a broader set of tools under one price.

The downsides include complexity in cost management and the need to adjust to Azure’s billing cycle.

Careful analysis is recommended to choose the right capacity (F SKU) so that performance and user access needs are met without overspending.

Use Cases and Success Stories of Fabric Migration

Several organizations have already made the leap from Power BI Premium to Microsoft Fabric. These real-world case studies highlight the motivations for migration and the benefits achieved.

Flora Food Group – Consolidation and Real-Time Insights

Flora Food Group, a global plant-based food company, was juggling Synapse, Data Factory, and Power BI as separate tools. Too many moving parts. They decided to consolidate everything into Fabric.

The move wasn’t rushed. They ran Fabric alongside their legacy stack and started with the big datasets. They used a medallion architecture (bronze-silver-gold) in OneLake to build a single source of truth.

From there, the upside came fast:

• Unified setup — reporting, engineering, science, and security in one stack
• Better reporting — centralized semantic models made data reuse easy
• Direct Lake — killed the need for scheduled refreshes; reports now pull fresh data near real time
• Lower waste — idle compute from one workload now powers another
• Faster BI teams — integrated tools meant fewer handoffs and less prep time

According to their Head of Data & Insight, the migration simplified their architecture and cut costs, while boosting capability. They see it as a strategic step toward what’s next: AI-powered analytics with Fabric Copilot.

BDO Belgium – Scalable Analytics for Mergers & Acquisitions

BDO Belgium was hitting walls with Power BI Premium, especially during M&A due diligence, where speed and clarity are non-negotiable.

So they built a new analytics platform on Fabric. They called it Data Eyes.

The shift paid off:

• Faster insights — better performance on large, complex datasets
• Self-service access — finance teams explored data without writing code
• One interface — familiar to users, powerful at scale
• Simpler backend — IT maintains one platform, not a patchwork

Fabric gave them what Power BI alone couldn’t: a system that handles scale and puts data in the hands of non-technical users.

For BDO, it wasn’t just an upgrade; it changed how the business works with data.

Other Early Adopters

Many organizations that were already invested in the Microsoft data stack find Fabric a natural progression. 

Some companies reported that Fabric’s unified approach streamlined their data engineering pipelines and BI. They cite benefits like reducing data duplication (thanks to OneLake) and easier enforcement of security in one place rather than across multiple services. 

Fabric’s integration of AI (Copilot for data analysis) is seen as an advantage. 

The pattern is that companies migrating from Power BI Premium experience improvements in data freshness, collaboration, and total cost of ownership when they leverage the full Fabric ecosystem of tools.

Value comes from utilizing Fabric’s broader capabilities rather than treating it as a like-for-like replacement of Power BI Premium. 

Organizations that approach the migration as an opportunity to modernize their data architecture (as Flora did with medallion architecture and real-time data, or BDO did with an intuitive analytics app) tend to reap the most benefits. They achieve not just a seamless transition of existing reports, but also new insights and efficiencies that were previously difficult or impossible with the siloed tool approach.

Implications of Not Migrating to Fabric

Given Microsoft’s strategic direction, companies that choose not to migrate from Power BI Premium to Fabric face several implications in terms of features, support, and long-term viability.

Feature Limitations

Fabric isn’t just the next version of Power BI. It’s a superset. Staying on Power BI Premium means missing the features Microsoft is building for the future.

No OneLake. No Direct Lake. No unified data layer. No Spark workloads. No Copilot. No built-in AI. Those are Fabric-only.

If you stay on Premium, your analytics stack stays frozen. Fabric keeps evolving: with deeper integration, faster performance, and cloud-scale features.

You can bolt on Azure services to replicate some of it, but that means extra setup, extra cost, and more moving parts.

Support and Updates

Microsoft is ending Power BI Premium per capacity SKUs. New purchases stop mid-2024. Renewals end in 2025.

What that means: you’ll need to move to Fabric if you want to keep using the platform.

There’s a temporary bridge: existing Premium customers can access some Fabric features inside their current capacity. But that’s a short-term patch. Not a strategy.

Once your legacy agreement runs out, so does your support. No new features. No roadmap. Just a countdown to disruption.

Fabric is the future. Microsoft’s made that clear.  

Potential Cost of Inaction

Delaying Fabric may seem easier in the short term, but the cost shifts elsewhere.

Power BI Report Server won’t be bundled once Premium SKUs are retired. It will require separate licensing through SQL Server Enterprise + SA.

Fabric also consolidates multiple tools (ETL, warehouse, reporting) into a single platform. Staying on the old stack means paying for them separately.

Microsoft is offering 30 days of free Fabric capacity during transition. After that, migration gets more expensive and less flexible.

Long-Term Roadmap Alignment

After 2025, support for legacy Premium issues could slow down - because engineering focus will be on Fabric. Eventually, the Power BI Premium brand itself may disappear.

Holdouts will face a bigger, messier migration later: with more change to absorb, less time to adapt.

Early movers get the opposite: smoother transition, room to adjust, and a seat at the table. Microsoft is still shaping Fabric. Companies that migrate now can influence what comes next.

Choosing not to migrate to Fabric is not a risk-free stance. In the immediate term (for those with existing Premium deployments), it means missing out on new capabilities and efficiencies. In the medium term (by 2025), it becomes a support risk as the old licensing model is phased out. While organizations can continue with Power BI Pro or Premium Per User for basic needs (these are not impacted by the capacity SKU retirement), larger scale analytics initiatives will increasingly require Fabric to stay on the cutting edge.

Therefore, companies should weigh the cost of migration against the cost of stagnation. Most will find that a planned migration, even if challenging, is the prudent path to ensure they remain supported and competitive in their analytics capabilities.
