Data Migrations

How do you migrate from legacy data platforms without disrupting your business?

Many organizations are weighed down by outdated tools like Informatica and Tibco, brittle ETL frameworks, and siloed warehouses that can’t scale. Passerelle’s data migration services provide a structured, low-risk approach to moving workloads into modern, cloud-native environments that support real-time analytics and AI.

Data Migrations

Move off legacy systems and into a modern, scalable data platform.

Why Data Migrations Matter

Legacy systems create high costs, operational inefficiencies, and roadblocks to innovation. As licensing fees increase and integrations become harder to maintain, organizations risk falling behind. Migrating to a modern environment reduces overhead, streamlines pipelines, and unlocks opportunities for advanced analytics.

With modern data migrations you can:

  • Retire expensive legacy platforms like Informatica and Tibco.
  • Consolidate siloed data into a governed, cloud-native environment.
  • Reduce operational risk with standardized, tested migration frameworks.
  • Establish a scalable foundation for analytics, machine learning, and AI.

How It Works

Every migration project balances risk reduction with modernization goals. Passerelle begins by cataloging existing workloads and identifying critical pipelines. Our team then uses reverse engineering and proven migration frameworks to safely move jobs into modern architectures, ensuring functionality is preserved and performance is improved. Throughout the process, governance and security controls are embedded to protect data integrity. Once migration is complete, organizations gain a clean, scalable environment that supports both everyday ingestion needs and advanced use cases.

Customer Testimonials

“Knowing that we are using a product that can scale and that can become very resilient is very important. In less than three years, we have become the largest single one stop place for material sampling in the world.” Juan Lopez, Executive Vice President of Engineering at Material Bank

Legacy Platform Replacement

Eliminate reliance on expensive ETL platforms such as Informatica and Tibco. Migration frameworks reduce downtime while ensuring a smooth transition to cloud-native solutions.

Workload Modernization

Rebuild brittle ETL jobs into scalable pipelines that handle both batch ingestion and real-time processing. Standardized blueprints ensure repeatability and lower risk.

Warehouse Consolidation

Bring siloed data together in a single, governed warehouse. Consolidation improves visibility, reduces redundancy, and strengthens trust in organizational data.

Governed Migrations

Protect data integrity with embedded governance, quality checks, and observability. Compliance is built in, ensuring migrated workloads are auditable and secure.

AI-Ready Architecture

Complete migrations with an environment that is optimized for analytics, machine learning, and AI adoption. Modern pipelines and governance lay the groundwork for future initiatives.
