Consolidate Your Models: Australia's Semantic Migration Specialists
Microsoft has built a first-party migration path from Azure Analysis Services to Power BI and openly calls Power BI and Fabric semantic models the future of enterprise semantic modelling. On-premise SSAS and Azure Analysis Services estates are being consolidated into the platform, and the Premium-to-Fabric capacity shift is accelerating it. SureLogic does this work as a named capability. We assess your model estate, convert multidimensional cubes to tabular where needed, refactor DAX and partition strategy, rebind your reports and cut over without downtime. You consolidate onto the platform Microsoft is investing in - and land one step from a modern semantic layer your AI can use.
Microsoft's Direction
You consolidate onto Power BI and Fabric semantic models, the platform Microsoft is investing in and frames as the future, rather than maintaining an Analysis Services estate being wound down.
Cubes Made Tabular
We convert multidimensional cubes to tabular models, preserving the measures, hierarchies and relationships your business relies on while moving to the engine Power BI is built around.
Refactored, Not Moved
We refactor DAX, relationships and partition strategy for the new platform, fixing years of accumulated inefficiency, so you land a faster, cleaner model rather than a relocated one.
No Downtime Cutover
Reports are rebound and validated against the originals, with a staged, reversible cutover run in parallel, so users keep their reports and the business never loses access during the move.
One Step from AI
We structure the migrated models to serve a governed semantic layer and ground AI tools, so you finish ready for conversational analytics and agents, not just dashboards.

Our SSAS Migration Services
Model Estate Assessment
Start by understanding every model you are moving. We assess your SSAS and Azure Analysis Services estate - the tabular and multidimensional models, their size, complexity, dependencies and the reports bound to them. We document what each model does and flag what can be retired or consolidated. You get a clear migration roadmap that says which models move as-is, which need conversion, and how to sequence the work without disrupting the business.
Multidimensional to Tabular Conversion
Bring multidimensional cubes into the modern tabular world. Where you still run multidimensional SSAS, we convert those cubes to tabular models that Power BI and Fabric are built around, preserving the calculations and structures your business relies on. Multidimensional-to-tabular is specialised work that defeats most generalists; we handle the measure logic, hierarchies and relationships so nothing of value is lost, and your reporting gains the performance and flexibility of the tabular engine.
DAX & Partition Refactoring
Refactor the model so it performs on the new platform. A faithful migration is not a copy - we refactor your DAX, relationships and partition strategy for Power BI and Fabric, fixing the inefficiencies that built up over years of SSAS development. Partitions are redesigned for the new capacity model, slow measures are tuned, and the model is structured for how Power BI actually queries it. You land a faster, cleaner semantic model, not just a relocated one.
Report Rebinding & Cutover
Move the reports across without a reporting blackout. We rebind your Power BI, Excel and other reports to the migrated models, validating that every figure reconciles against the original. Cutover is staged and reversible, run in parallel until the business trusts the new platform. Users keep the reports they rely on, now served by a consolidated semantic model on the platform Microsoft is investing in, with no downtime and no surprises.
Semantic Layer & AI Readiness
Land your models one step from a true semantic layer and AI. Migrating is the moment to set your semantic model up not just for reporting but for what comes next. We structure definitions, security and metadata so the model can serve a governed semantic layer and ground AI tools and agents reliably. You finish the migration with consolidated, modern models that are ready for conversational analytics and agent access, not just dashboards.

Our Proven SSAS Migration Framework
Our senior modellers assess your estate, convert and refactor your models, and cut over to Power BI and Fabric without downtime.

Model Estate Assessment
We assess your SSAS and Azure Analysis Services models - tabular and multidimensional - their complexity, dependencies and bound reports, and flag what to consolidate or retire. You receive a migration roadmap that says which models move as-is, which need multidimensional-to-tabular conversion, and how to sequence the work without disrupting reporting.
Convert, Refactor & Rebind
2
We convert multidimensional cubes to tabular where needed, refactor DAX and partition strategy for Power BI and Fabric, and rebind your reports to the migrated models. Every figure is validated against the original. The model is not just relocated but improved, structured for the new platform's performance and capacity model.
Cutover & AI-Ready Handover
3
We run the migrated models in parallel until the business trusts them, cut over without downtime, and decommission the old Analysis Services estate. We structure the result so it can serve a governed semantic layer and AI tools, and hand over documentation. You finish consolidated on the modern platform and ready for what comes next.
SSAS to Power BI Migration FAQs
Why is Microsoft moving Analysis Services to Power BI and Fabric?
Microsoft has built a first-party migration path from Azure Analysis Services to Power BI and frames Power BI and Fabric semantic models as the future of enterprise semantic modelling. Investment, new capability and the Premium-to-Fabric capacity shift are all flowing to the unified platform, while standalone Analysis Services is consolidated in. Migrating now aligns you with where Microsoft is heading and avoids maintaining an estate on a platform being wound down.
The destination is a governed model - see our semantic layer consulting page.
Do we need to convert multidimensional models to tabular?
If you still run multidimensional SSAS, yes - Power BI and Fabric are built around the tabular engine, so multidimensional cubes are converted to tabular models as part of the migration. It is specialised work: we preserve the measures, hierarchies and relationships your business relies on while moving to the modern engine. Tabular models that are already in place migrate more directly, with refactoring rather than conversion.
Will our reports keep working after the model migration?
Yes - we rebind your Power BI, Excel and other reports to the migrated models and validate every figure against the original before cutover. The move is staged and reversible, run in parallel until the business trusts the new platform, so users keep the reports they rely on with no downtime. The reports are served by a consolidated semantic model on the modern platform rather than the retiring Analysis Services estate.
Is this the same as a Power BI report migration?
No - this is semantic model migration, the layer beneath the reports, which is squarely SureLogic's named capability. We migrate and refactor the SSAS and Analysis Services models themselves, where the calculations and business logic live. Report Simple handles the Power BI report and dashboard delivery on top. Splitting the model work and the report work across specialists is what gets both done properly.
For the platform underneath, see our data warehouse consulting page.
What do we gain beyond consolidation by migrating?
A migration done well leaves you with faster, cleaner models and a foundation ready for AI, not just a relocated estate. We refactor inefficient DAX and partitions, and structure the model so it can serve a governed semantic layer and ground conversational analytics and agents reliably. You consolidate onto the platform Microsoft is investing in, and finish one step from the semantic layer and AI offers that build on it.
