In the fast-paced telecom sector, staying on supported, high-performance infrastructure isn't just a technical choice—it's a business necessity. For a global digital solutions leader, the looming end-of-support for their legacy ETL platform was the catalyst for a total system refresh.

Navigating a Dual Transition

‍

The objective was ambitious: upgrade from Jaspersoft Talend 7.3 to Qlik Talend 8 while simultaneously migrating database workloads from Oracle to PostgreSQL. This required handling 315 unique ETL jobs and massive data volumes without letting the business skip a beat.

‍

The Engineering Approach

‍

Working with Exponentia.ai, the client followed a rigorous, phased approach to ensure technical success:

• Clean-Slate Assessment: All 315 jobs were assessed and categorized to simplify design and remove unnecessary components.

• Code Conversion: Our team handled the heavy lifting of converting Oracle-specific SQL into PostgreSQL-compatible logic, ensuring no loss in functional integrity.

• DevOps Excellence: By moving to a Git-integrated environment, we ensured that every artifact is version-controlled and deployed securely through the Talend Administration Center.

‍

Measurable Results

‍

The migration delivered more than just a software update; it delivered a performance engine. High-volume jobs now run 30-40% faster than before, and the move to PostgreSQL has significantly reduced dependency on legacy database environments.

‍

The Path Forward

‍

This modernization project demonstrates how large-scale ETL initiatives can be delivered with zero disruption when technical rigor meets strong ownership. The client now operates on a reusable reference model that is scalable, secure, and ready for future growth.
