Oracle Discoverer is end-of-life. OBIEE is being de-emphasized. And your organisation is already standardising on Microsoft 365, Azure, and Power BI. We design and deliver Oracle BI migrations to Power BI — rebuilding your RPD logic, Discoverer workbooks, and BI Publisher outputs as governed, high-performance models on Azure and Microsoft Fabric.
Is Your Oracle BI Migration More Complicated Than You Planned?
Your OBIEE Cannot Simply Be Copied Into Power BI
OBIEE’s three-layer semantic model encodes joins, aggregations, security rules, and calculated measures across hundreds of objects. None of it maps directly to Power BI’s tabular model. Teams that ignore this and migrate report by report end up with inconsistent numbers, broken hierarchies, and a model nobody can maintain.
Oracle Discoverer Is End-of-Life
Discoverer is beyond end-of-life with no supported upgrade path. Your teams are running business-critical workbooks on unsupported infrastructure. The longer it runs, the greater your security exposure, your compatibility risk, and your dependency on staff who still know how to use it.
Your Security Model Will Not Survive a Naive Migration
OBIEE RPD security, Oracle EBS responsibilities, and Discoverer business area permissions do not translate automatically to Power BI. A direct copy either exposes data to the wrong users or locks out the right ones. In financial services and healthcare, it is a compliance failure.
Power BI Pointed at Oracle EBS Will Be Painfully Slow
OBIEE and Discoverer were engineered for Oracle databases — using materialized views, summary tables, and query push-down to deliver performance. Connect Power BI directly to Oracle EBS and you get timeouts, lock contention, and very unhappy DBAs. The performance does not fix itself.
Pixel-Perfect Reports Are an Afterthought — Until They Are a Crisis
BI Publisher layouts, parameterised PDF outputs, and scheduled distribution runs are often left out of migration scope until the last week of the project. Power BI handles these with Paginated Reports and Power Automate — but they take deliberate design.
Our Method – Oracle BI Migration, Done Right
We don’t just move reports; we redesign the foundations that your reporting is built on.
Most BI migration projects fail for the same reason: they treat OBIEE or Discoverer as a report catalogue and Power BI as the destination. We treat the migration as what it actually is — a semantic model redesign, a data architecture decision, and a controlled transition program.
Semantic Layer First, Reports Second
We begin by cataloguing your RPD or Discoverer SQL logic — subject areas, joins, aggregation rules, calculated measures, and security filters. That logic is redesigned into a star-schema tabular model with conformed dimensions and reusable DAX measures. Your reports are then built on top of a model that works — not the other way around.
Architecture Matched to Your Situation
Not every Oracle BI estate needs the same solution. We apply a structured decision framework — choosing between full semantic redesign, SQL subject-area lift, connector passthrough, or a data-platform-first approach on Azure Synapse or Microsoft Fabric — based on your Oracle ERP environment, your Azure roadmap, and your timeline for decommissioning Oracle BI.
Security and Compliance Built In From Day One
EBS responsibilities, OBIEE RPD-level security, and Discoverer business area permissions are mapped and redesigned into Power BI RLS roles and Entra ID groups before the first report is built. We design for auditability — so your security model holds up to scrutiny from IT, compliance, and your auditors.
Parallel Run and Controlled Decommission
We run your old Oracle BI environment and the new Power BI environment side by side. Automated regression tests compare outputs on every key measure and report, flagging variances above agreed thresholds. Oracle BI is switched off only after business owners and auditors have signed off — with rollback options in place.
Four Ways to Migrate from Oracle BI to Power BI — We Help You Choose the Right One
There is no single correct migration path.
The right approach depends on your Oracle BI estate, your Azure roadmap, your risk appetite, and how fast you need to get off legacy infrastructure. We apply a structured decision framework and recommend the archetype — or combination — that fits your situation.
A. Semantic Layer Redesign
When It FitsLarge OBIEE RPD with multiple subject areas. Organisation is moving to Azure or Fabric and is ready to modernise the architecture, not just the front end.
What We DoWe re-implement your RPD logic as a star-schema tabular model in Power BI or Azure Analysis Services. Business rules are rewritten in DAX. A curated data layer on Synapse or Fabric replaces Oracle summary tables.
B. SQL Subject-Area Lift
When It FitsDiscoverer-heavy estate with hundreds of workbooks. The priority is getting off end-of-life infrastructure fast. Semantic refactoring comes in a later phase.
What We DoWe extract SQL from your Discoverer workbooks and drop it into Oracle database views or a staging layer. Power BI reports connect to those views as subject areas. A second wave rationalises and consolidates the model.
C. Connector Passthrough
When It FitsSignificant investment in OBIEE or Oracle Analytics Cloud (OAC). No business mandate yet for deep architectural change in wave one.
What We DoWe use a connector (such as BI Connector) to expose your OBIEE or OAC subject areas inside Power BI. You get a modern, self-service front end without touching the Oracle semantic layer — for now.
D. Data Platform First
When It FitsOracle BI decommission is part of a wider Azure analytics or ERP modernisation programme. A new data platform is being built anyway.
What We DoWe build a Data Lake and Synapse or Fabric warehouse, set up ELT pipelines from Oracle EBS, and layer Power BI and Paginated Reports on top. Discoverer and OBIEE retirement is a controlled outcome.
Whether you need a rapid infrastructure exit or a total architectural transformation, we make sure your Oracle BI decommission is a controlled, successful outcome.

What a Successful Oracle BI Migration Looks Like — And What Trips Teams Up
This is a complex migration. The organisations that get it right treat it as a programme. The ones that struggle treat it as a report-migration project.

Frequently Asked Questions about Oracle BI to Power BI Migration
How is migrating from OBIEE to Power BI different from other BI migrations?
OBIEE’s RPD encodes joins, aggregation rules, security filters, and business logic across three layers — physical, business model, and presentation. None of that has a direct equivalent in Power BI’s tabular model. Migrating OBIEE means redesigning your semantic layer from scratch, not translating reports. Teams that skip this step end up with models that produce wrong numbers and break under any meaningful change.
Can Power BI fully replace Oracle Discoverer?
Yes — but the path matters. The fastest route off Discoverer is a SQL lift: extract the SQL from your workbooks, push it into Oracle reporting views, and connect Power BI on top. That gets you off end-of-life infrastructure quickly. A full semantic redesign consolidates that logic into a proper tabular model for long-term governance. We help you choose the right approach based on your workbook volume, your timeline, and your architecture ambition.
How do you handle security when moving from OBIEE or Discoverer to Power BI?
We map every OBIEE RPD security setting and Oracle EBS responsibility to the equivalent Power BI RLS role and Entra ID group — before any reports are built. Discoverer business area access is redesigned using AD groups and Power BI workspace roles. For healthcare and financial services clients, we document the access model explicitly so your compliance team and auditors can review and sign off.
Do you migrate Oracle BI Publisher reports and scheduled distributions?
Yes, and we scope this in wave one — not as an afterthought. BI Publisher pixel-perfect outputs are rebuilt as Power BI Paginated Reports using Report Builder. Scheduled distribution and PDF bursting logic is re-implemented with Power Automate and Power BI subscriptions. Leaving this to the end of a migration is one of the most common reasons projects hit a crisis at go-live.
How long does an OBIEE or Discoverer migration take?
It depends on RPD complexity, report volume, and your target architecture. A focused Discoverer SQL lift for a single business domain typically takes 4–8 weeks. A full OBIEE semantic redesign with multiple subject areas and a new data platform is a multi-wave programme of 4–9 months. We give you a realistic timeline estimate after a scoped discovery engagement — not before.
What happens during the parallel run phase?
Both Oracle BI and Power BI run live simultaneously for a defined period. We set up automated regression tests that compare outputs on key metrics, measures, and filtered views — and flag any variance above agreed thresholds. Business owners review the results. Oracle BI is not switched off until formal sign-off is received, and rollback options remain in place for a defined window after cutover.
What are the most common reasons Oracle BI migrations go over budget?
Five things come up repeatedly: underestimating the complexity behind the RPD or Discoverer SQL; treating security as a late-stage task; skipping the data layer design and pointing Power BI directly at Oracle sources; missing BI Publisher and scheduling scope; and changing the target architecture mid-programme. Our discovery and blueprint phases are designed specifically to surface these risks before they become cost overruns.
