Case Study: ABN AMRO achieves seamless Teradata-to-Azure Synapse migration with Datometry

ABN AMRO Accelerates Digital Transformation to Azure Synapse with Datometry

ABN AMRO, one of the largest retail banks in the Netherlands, sought to migrate its business-critical data warehouse from Teradata to Azure Synapse to achieve significant cost savings and cloud flexibility. The bank needed to avoid a lengthy, error-prone application rewrite, especially for models that were stringently regulated and would require recertification if altered. Their challenge was to complete this complex migration on an aggressive timeline with zero downtime for their business users.

Using the Datometry Hyper-Q platform, ABN AMRO translated SQL and API calls in real-time, allowing their unmodified applications to work directly with Azure Synapse. This approach from Datometry eliminated the need for a massive code rewrite, preserved their regulatory certifications, and enabled a small internal team to execute the project. As a result, ABN AMRO completed the full migration in under 10 months, seamlessly transitioning all business users without downtime, and realized considerable savings by decommissioning their legacy Teradata system.
