IBM Cognos to Power BI Migration – Structured, Validated, Business-Ready


Contact us

Your Cognos environment has years of reports, business logic, and security rules built up inside it. We deliver structured IBM Cognos to Power BI migration programs: from report inventory and semantic model redesign to security remapping, user enablement, and full Cognos decommission.

WHY

Is Your Cognos Environment Costing More Than It Delivers?

IBM Licensing Costs Keep Rising

Every Cognos renewal is a significant investment. Licensing, infrastructure, and specialist support costs stay high even as usage migrates to other tools. Most organisations find that a large share of their Cognos reports are rarely accessed.

Good Cognos Developers Are Hard to Find

Framework Manager, Report Studio, and TM1 require skills that are increasingly scarce. When a key developer leaves, institutional knowledge about how your reports and data models actually work often leaves with them.

Every Change Takes Too Long

Simple report changes that should take hours take days. Upgrades require extensive compatibility testing across your report catalogue. And every time IBM shifts its support roadmap, your team has to react.

Cognos Is Isolated from the Rest of Your Stack

Your organisation is investing in a new ERP, Microsoft 365, Azure, and potentially Microsoft Fabric. Cognos sits outside all of it — a separate platform with separate governance, separate identities, and separate costs.

OUR METHOD

Migrate from Cognos to Power BI Without Disrupting the Business

We don’t just rebuild your Cognos reports in Power BI. We assess what you have, design a Power BI environment that actually improves on it, and validate everything before Cognos is switched off.

01

Understand What You Have Before You Touch Anything

We inventory your full Cognos estate — reports, data packages, Framework Manager models, TM1 cubes, security rules, and actual usage data. Every report gets a decision: rebuild, consolidate, or retire. This step typically reduces migration scope by 30–40%.

02

Redesign for Power BI — Not a Cognos Clone

We redesign the semantic model for Power BI’s tabular architecture — star schemas, shared DAX measures, governed KPI definitions — rather than replicating Cognos logic inside a new tool. Business logic moves out of individual reports and into a shared, maintained model.

03

Validate Numbers, Then Decommission

Cognos stays live until Power BI passes validation — automated comparison of report outputs, stakeholder sign-off from BI and business owners, and documented resolution of every discrepancy. IBM licences are cancelled when parity is confirmed, not when the project timeline says so.

FULL-CYCLE MIGRATION SERVICES

From Cognos Assessment to Power BI Production

Assessment Icon

Cognos Estate Assessment & Migration Roadmap

We inventory your Cognos environment — reports, packages, cubes, and security rules — and classify every asset by value and complexity. Output: a prioritised Rebuild / Consolidate / Retire decision for every report, and a realistic migration roadmap.

Architecture Icon

Semantic Model & Data Architecture Design

We design the Power BI semantic model from the ground up — star schemas, shared DAX measures, and a governed data layer that replaces Framework Manager structures. TM1 cube logic is translated into tabular models or Fabric-native structures.

Migration Icon

Report Migration & Rebuild

We migrate your prioritised Cognos reports — list reports, crosstabs, dashboards, paginated outputs — into Power BI using structured rebuild and migration tooling. Complex business logic is re-implemented in the data model, not recreated at report level.

Security Icon

Security Remapping & RLS Design

We translate your Cognos security model into Power BI Row-Level Security, workspace permissions, and Microsoft Entra ID group mappings. Delivered as a documented, auditable security design before any user is moved across.

Validation Icon

Parallel Validation & User Acceptance

We run Cognos and Power BI in parallel with automated output comparison and structured sign-off from report owners. Cognos is decommissioned domain by domain as validation is confirmed — never all at once.

Enablement Icon

User Enablement & BI COE Design

We design the Power BI training programme for your team and build the governance model that prevents the new platform becoming as fragmented as the old one. Adoption is a delivery workstream, not an afterthought.

OUR STEPS

A Clear Path from Cognos to Power BI — in Stages

Cognos Assessment & Inventory
We map your full Cognos estate — reports, data packages, TM1 cubes, security rules, and usage logs. Every asset gets a Rebuild / Consolidate / Retire classification and a complexity score.
Outcome:
A scoped, realistic migration plan — and usually 30–40% less work than first assumed, once unused reports are identified for retirement.
Target Architecture Design
We design the Power BI environment: semantic model structure, DAX measure framework, workspace and governance model, and the data platform connections that replace Cognos data sources.
Outcome:
A Power BI architecture built for your organisation — not a replica of Cognos logic in a new tool.
Report Migration & Model Build
We migrate prioritised reports in phased waves — high-value and complex reports first, to surface edge cases early. The semantic model is built once and shared across all reports.
Outcome:
Production-ready Power BI reports built on a governed, maintainable model that your team can extend without specialist Cognos knowledge.
Security Remapping & Parallel Validation
Security rules are translated to Power BI RLS and Entra ID. Cognos and Power BI run in parallel, with automated output comparison and stakeholder sign-off required before cutover.
Outcome:
Users see exactly the right data in Power BI — validated against Cognos, documented for audit, and confirmed by the business before Cognos is touched.
Cutover, Enablement & Decommission
Users are moved to Power BI domain by domain, with training and support through the transition. IBM licences are cancelled as each domain confirms readiness. Cognos is retired on evidence, not on schedule.
Outcome:
A live Power BI environment, a trained team, and IBM licensing costs that are finally off the books.
OUR MICROSOFT AND COGNOS-FOCUSED EXPERTISE

Specialists in Cognos Migration, Experienced Across the Microsoft BI Stack

    FAQ

    Frequently Asked Questions about Cognos and Power BI

    Is there an automated way to convert Cognos reports to Power BI?

    Automation tools can accelerate parts of the migration — metadata extraction, basic layout recreation, and straightforward expression mapping. But they cannot interpret ambiguous business logic, redesign poor data models, or validate that numbers match. Every Cognos migration requires human analysis, semantic model redesign, and structured testing. Automation helps with speed; it does not replace the architectural work.

    How long does a Cognos to Power BI migration take?

    It depends on how many reports you have, how complex your data models are, and whether TM1 / Planning Analytics is in scope. A focused migration of a single business domain — 50–100 reports with well-understood data sources — typically takes 3 to 5 months. A full enterprise migration of a large Cognos estate usually runs 12 to 24 months as a phased programme. The assessment phase gives you a realistic timeline based on your actual environment.

    Do we need to rebuild every Cognos report in Power BI?

    No — and you shouldn’t try. Most Cognos estates contain a large number of reports that are rarely or never used. A structured inventory, scored by usage and business criticality, typically identifies 30–40% of reports that can be retired rather than migrated. Rebuilding only what matters reduces cost, timeline, and the risk of recreating a bloated report catalogue in a new tool.

    How does Cognos security translate to Power BI?

    Cognos controls access at the portal, package, and data row level — often through Active Directory groups. Power BI implements security through workspace permissions, app distribution, and Row-Level Security defined in the data model, all integrated with Microsoft Entra ID. The two models don’t map automatically — every security rule needs to be catalogued, redesigned, and validated. For regulated or finance-sensitive reporting, this is a first-class deliverable, not a configuration step.

    What happens to TM1 and Planning Analytics in the migration?

    TM1 and Planning Analytics cube logic — allocations, hierarchies, multi-currency structures, write-back — cannot be lifted directly into Power BI. The cube logic needs to be understood, documented, and re-implemented: either as DAX measures and tabular models in Power BI, or as upstream transformation logic in Fabric or Azure. Finance teams using TM1 for planning and reporting need to be involved in validation from the start, not presented with the result at the end.

    Can we keep some Cognos reports and migrate the rest?

    Yes, and for some organisations this is the right approach — particularly for regulated or statutory reports where changing the layout or output format requires formal re-approval. We design the migration scope to reflect this: some domains move to Power BI fully, others may be retained in Cognos temporarily or permanently. What matters is that the decision is made deliberately, with a clear decommission plan for each retained report, rather than Cognos persisting indefinitely by default.
