Your organisation is already running on Microsoft 365, Azure, and Teams. Tableau sits outside that stack – and the licensing bill keeps growing. We design and deliver Tableau to Power BI migrations – rebuilding your dashboards, calculated fields, and data models as governed, high-performance semantic models on Power BI and Microsoft Fabric.
Is Your Tableau Investment Starting to Work Against You?
Tableau Licenses Cost More as Your User Base Grows
Tableau’s per-user pricing model makes sense at small scale. Once your organisation grows – and more business users need access to reports – the cost compounds fast. For companies already paying for Microsoft 365, running a parallel Tableau estate is hard to justify at budget review.
Your Tableau Workbooks Are Fragmented and Hard to Govern
Dashboards built by different teams over different years. Calculations that don’t agree. KPIs that mean different things depending on which workbook you open. Tableau’s flexibility that once felt like freedom now feels like a governance problem nobody wants to own.
Tableau Sits Outside Your Microsoft Stack – and It Shows
Your teams work in Teams, Excel, SharePoint, and Azure every day. Tableau doesn’t embed cleanly, doesn’t share a security model with Entra ID, and doesn’t connect to Fabric or Copilot. Every integration is a workaround. Every new Microsoft feature your data team wants to use requires Tableau to be in the room first.
Your AI and Fabric Roadmap Can’t Move Forward
Microsoft Copilot in Power BI, Fabric lakehouses, and shared semantic models all require data to live inside the Microsoft ecosystem. As long as your primary BI layer is Tableau, that roadmap stays blocked. The migration is not the destination – it’s the prerequisite.
Our Method – Tableau to Power BI Migration, Done Right
We don’t just convert dashboards; we rebuild the foundations your reporting depends on.
Most Tableau migration projects fail for the same reason: teams treat it as a visual cloning exercise and Power BI as a drop-in replacement. We treat the migration as what it actually is – a semantic model redesign, a data architecture decision, and a controlled transition program.
Data Model First, Dashboards Second
We start by inventorying your Tableau environment – workbooks, data sources, calculated fields, LOD expressions, and extract schedules. That logic is redesigned into a star-schema semantic model with reusable DAX measures. Your dashboards are built on top of a model that works – not rebuilt one by one with no foundation underneath.
Migration Scope Matched to Your Situation
Not every Tableau estate needs the same approach. We apply a structured assessment – deciding what gets migrated, what gets redesigned, what gets retired, and whether automation accelerators make sense for your workbook complexity – before a single report is touched.
Governance and Security Built In From Day One
Tableau permissions and data source access are redesigned into Power BI Row-Level Security and Entra ID groups before any reports go live. We design for auditability – so your security model holds up to scrutiny from IT, compliance, and your organisation’s administrators.
Parallel Run and Controlled Cutover
Tableau stays live while Power BI is validated alongside it. Automated checks compare key metrics between both platforms, flagging variances above agreed thresholds. Tableau is decommissioned only after business users have signed off – with a rollback option retained.
From Tableau Inventory to Power BI Production – Full-Cycle Migration Delivery
From the initial audit to the final switch-over, we handle the heavy lifting.
We are specialists in BI migrations and Power BI delivery. We assess the Tableau environment, design the target Power BI architecture, build the semantic models, and manage validation before a single dashboard goes live.
Tableau Environment Inventory and Assessment
We catalogue your full Tableau estate – every workbook, data source, calculated field, LOD expression, extract schedule, user group, and permission set. Each artefact is classified by complexity, business criticality, and migration approach. Output: a realistic scope, phased delivery plan, and effort estimate based on your actual environment – not a generic assumption.
Target Power BI Architecture Design
We design the target Power BI environment from the ground up: semantic model structure, star schema transformations, workspace organisation, dataset strategy, and whether Microsoft Fabric or Azure Synapse belongs in the picture. Architecture drives every decision that follows.
Data Model and DAX Engineering
We translate Tableau calculated fields, LOD expressions, and table calculations into DAX measures built on a governed semantic model. Multiple Tableau workbooks drawing from the same data are consolidated into a single reusable dataset – replacing fragmented logic with a single source of truth.
Dashboard Conversion and UX Redesign
We migrate Tableau dashboards to Power BI – combining automated conversion tools where they save time with manual redesign where quality demands it. Migration is also an opportunity to fix long-standing UX issues: we run workshops with business users to define the target, not just clone what existed.
Testing, Validation and Cutover Management
We run Tableau and Power BI side by side for a defined period. Automated regression checks compare outputs on every key metric, flagging variances above agreed thresholds. Structured UAT with business users captures discrepancies before they become post-go-live incidents. Tableau is switched off only when sign-off is received.
Training, Governance and Post-Migration Optimisation
We deliver role-based training for report builders and consumers, set up governed Power BI workspaces and apps by business domain, and document semantic models, naming conventions, and access policies. Ongoing optimisation – refresh tuning, model performance, Fabric and Copilot readiness – is available as a continued engagement.
We don’t hand over a migration and disappear. We stay accountable until the dashboards work, the numbers match, and your team is confident running Power BI without us.
A Clear Migration Path – Tableau to Power BI in Stages
Experts in Power BI. Experienced Across the Full Migration Stack.
We know both sides of the migration – the Tableau environment you are leaving and the Microsoft platform you are moving to. Our teams work across the full source and target stack, from Tableau Server administration to Microsoft Fabric lakehouse design.
What a Successful Tableau to Power BI Migration Looks Like – And What Trips Teams Up
This is not a simple report export. The organisations that get it right treat it as a structured programme. The ones that struggle treat it as a dashboard conversion project.

Frequently Asked Questions about Tableau to Power BI Migration
Is there a one-click way to convert Tableau dashboards to Power BI?
Partially. Automated migration accelerators can handle layout conversion, simple visuals, and basic measures – and some vendors claim 70-90% automation rates. In practice, complex calculated fields, LOD expressions, custom visuals, and non-standard data sources still require manual work. We evaluate which accelerators make sense for your specific Tableau estate and combine them with manual redesign where automation produces unreliable output.
How accurate are automated Tableau to Power BI conversion tools?
For simple dashboards with standard visuals and straightforward calculations, accuracy is reasonable. For workbooks with complex LOD expressions, blended data sources, or Tableau Prep dependencies, automated tools consistently leave gaps that require manual correction. We use them where they save time and redesign by hand where they don’t – rather than trusting the output without validation.
Do we need to rebuild every dashboard from scratch?
Not necessarily. The assessment phase determines what gets migrated, what gets redesigned, and what gets retired. Simple dashboards can often be converted with minimal rework. Complex ones – particularly those with heavy calculation logic or custom interactions – need deliberate redesign. Migration is also an opportunity to retire dashboards that nobody uses and consolidate ones that overlap.
How do you handle complex Tableau calculations and LOD expressions?
We translate Tableau calculated fields, table calculations, and LOD expressions into DAX measures built on a proper semantic model. This is one of the hardest parts of any Tableau to Power BI migration – DAX and Tableau’s calculation engine work differently. We use translation playbooks developed across previous migrations and validate every measure against the original Tableau output before sign-off.
Can we keep Tableau running while we roll out Power BI?
Yes – and we recommend it. We run both platforms in parallel for a defined period, with automated regression checks comparing key metrics between them. Tableau stays live and read-accessible while Power BI is validated domain by domain. Tableau is decommissioned incrementally, not in a single cutover, which significantly reduces risk.
What skills does our internal team need during and after the migration?
During the migration, your team needs to be available for UAT, data validation, and sign-off – the business context only they can provide. After go-live, report builders will need Power BI Desktop skills and DAX fundamentals. We deliver role-based training as part of the engagement and document semantic models and governance standards so your team is not dependent on us to maintain what we built.
How long does a typical Tableau to Power BI migration take?
It depends on the size and complexity of your Tableau estate. For 20-50 dashboards with a focused scope, experienced teams typically deliver in 6-10 weeks. For larger estates of 100+ workbooks across multiple business domains, a phased programme of 3-6 months is more realistic. We give you a timeline estimate after a scoped discovery engagement – not before, because estimates made without an inventory are rarely accurate.
How do you ensure the numbers match between Tableau and Power BI?
We set up automated regression checks that compare key metrics and filtered views between both platforms, flagging any variance above agreed thresholds. Business users then review the results in structured UAT. Every critical KPI is signed off before Tableau is decommissioned. Number matching is the gate – not the project deadline.
Can you also help with data warehousing and Microsoft Fabric, not just dashboards?
Yes. Multishoring works across the full Microsoft data stack. If your migration requires a new data layer – whether that is Azure Synapse, Microsoft Fabric, or a modernised SQL warehouse – we design and build it as part of the engagement. Many Tableau migrations are the starting point for a broader analytics modernisation, and we support the full journey.
What if we only want to migrate part of our Tableau estate?
That is a common and sensible starting point. We can scope a partial migration – by business domain, by priority tier, or by a defined set of dashboards – without committing to a full estate replacement upfront. The assessment phase identifies which workbooks to tackle first, and the engagement can expand in subsequent waves once the first migration is validated and live.
