What Steps Should I Follow to Move from Cognos to Looker?

Migrating from Cognos Analytics to Looker is increasingly becoming a strategic decision for organizations aiming to modernize their business intelligence (BI) capabilities. Looker offers a cloud-native, scalable, and intuitive analytics platform that empowers organizations to make data-driven decisions faster, streamline reporting, and improve analytics efficiency. At Squareshift, we specialize in guiding enterprises through this transformation with certified Looker experts, proven migration experience, and a strong track record recognized by clients and industry analysts.

Here’s a step-by-step approach to ensure a smooth migration:

1. Assess Your Current Cognos Environment

Before starting the migration, it’s crucial to conduct a thorough assessment of your existing Cognos dashboards, reports, and data models. This includes:

• Inventorying all reports and dashboards.
• Identifying high-priority reports for immediate migration.
• Understanding complex calculations, filters, and custom scripts.
• Evaluating data sources and integrations.

Example: One financial services client worked with Squareshift to map over 200 Cognos reports, enabling a seamless prioritization for migration and reducing redundant reports by 30%.

2. Define Your Migration Strategy

Once the assessment is complete, define a migration strategy aligned with business goals:

• Determine whether to migrate dashboards as-is or redesign them for Looker’s modern architecture.
• Decide on phased migration vs. full-scale migration.
• Set measurable KPIs such as report generation time reduction or data query performance improvements.

Benefit: A structured approach ensures that reporting becomes faster and analytics efficiency improves, delivering measurable ROI.

3. Data Model Mapping and Transformation

Looker operates on a semantic modeling layer (LookML), different from Cognos’ data model. This step involves:

• Mapping Cognos metadata to Looker dimensions, measures, and views.
• Transforming complex calculations and aggregations into LookML.
• Validating data consistency to ensure accurate reporting.

Case Study: Squareshift helped a retail client migrate their inventory reporting, reducing report preparation time from 5 hours to under 30 minutes, thanks to centralized data management in Looker.

4. Dashboard and Report Migration

Next, rebuild dashboards and reports in Looker:

• Replicate high-priority dashboards with improved visualizations.
• Optimize for self-service analytics, allowing business users to explore data independently.
• Test for accuracy, performance, and usability before full rollout.

Pro Tip: Phased migration helps minimize disruption, especially for enterprises with large-scale reporting needs.

5. User Training and Change Management

A successful migration includes preparing your team:

• Conduct Looker training sessions for end-users.
• Provide documentation and best practices.
• Encourage adoption through hands-on support and continuous feedback loops.

Result: Teams become more self-sufficient, reducing dependency on IT while speeding up decision-making.

6. Monitor and Optimize

Finally, monitor performance and optimize workflows:

• Track report usage and performance metrics.
• Refine dashboards based on user feedback.
• Explore advanced analytics features like embedded analytics or predictive modeling.

Impact: Organizations experience cost reduction through optimized cloud resources and improved ROI from analytics investments.
