Migration Strategies (What Actually Happens)

Migrating from Power BI Premium to Microsoft Fabric offers a few distinct paths, each with its own considerations. The most common approach involves reassigning your workspaces to the new Fabric capacity.

Microsoft has also provided tools and guidance to automate parts of this process, making the transition smoother for many organizations. 

1. Automated Migration

For many scenarios, the migration can be as simple as reassigning existing Power BI workspaces to an F-SKU Fabric capacity (via UI or REST). This automated process is designed to minimize disruption and allow for a quick transition.

During your current Power BI Premium agreement renewal, you can work with your Microsoft account representative to transition your P-SKU purchase to an F-SKU purchase. Once the F-SKU capacity is provisioned, you can reassign your workspaces directly within the Power BI service.

2. Manual Migration Considerations

While automated migration is straightforward for many Power BI assets, there are specific considerations for certain scenarios, particularly when dealing with non-Power BI Fabric items or if you need to move workspaces between Azure regions.

Workspaces containing non-Power BI Fabric items (e.g., data engineering notebooks, data warehouses) cannot be moved across regions in-place. In such cases, these items must be deleted, the workspace moved, and items recreated in the new region.

3. Grace Period for Transition

Microsoft has provided a grace period for organizations transitioning from Power BI Premium to Microsoft Fabric. This period gives you time to reassign workspaces to F-SKU capacity without losing access.

This flexibility is designed to ensure a controlled and well-planned migration, giving organizations ample time to validate their new setup.

Capacity Sizing & Cost Optimization in Microsoft Fabric

One of the most significant changes when moving to Microsoft Fabric is the shift in how capacity is managed and billed. Understanding Capacity Units (CUs) and the various F-SKUs is crucial for optimizing performance and controlling costs.

1. Understanding Capacity Units (CU) and SKUs

Microsoft Fabric capacities are measured in Capacity Units (CUs), which represent the compute power available for each SKU. The F-SKUs (e.g., F2, F4, F8, F16, etc.) correspond to different levels of CUs, with higher F-SKUs offering more compute power. This granular approach allows organizations to select a capacity that precisely matches their workload requirements.

2. Pay-as-you-go vs. Reserved Capacity

Microsoft Fabric offers both pay-as-you-go and reserved capacity options. The pay-as-you-go model provides flexibility, allowing you to scale your capacity up or down based on demand and only pay for what you use.

This is particularly beneficial for fluctuating workloads or during initial migration phases. For more stable and predictable workloads, reserved capacity can offer significant cost savings over time. 

3. Using the Fabric Capacity Estimator

To assist with capacity planning and cost estimation, Microsoft provides the Fabric Capacity Estimator. This tool helps predict the capacity needed for various Microsoft Fabric workloads, optimizing CU consumption, cost, and performance. It’s recommended to use this tool to make informed decisions about your F-SKU selection.

4. Hidden Costs and Optimization

While F-SKUs are primarily compute-focused, it’s important to be aware of potential hidden costs, particularly related to storage. Every byte of data in Microsoft Fabric lands in OneLake, which is billed separately; soft-delete/BCDR retention may also incur charges.

Therefore, effective data management and optimization strategies for OneLake storage are essential to control overall expenses. Additionally, optimizing your data models, queries, and refresh schedules can significantly reduce CU consumption and, consequently, your costs.
