David Yurman had three legacy data warehouses, leading to data silos, mismatches, and the burden of maintaining pipelines across three tech stacks. Using dbt with multi-project architecture and data contracts, we’ve made significant progress in consolidating our platform. Inspired by the "strangler" approach from microservices, we built legacy facades, enabling a smooth transition for consumers and avoiding previous launch failures. In this talk, we’ll share our new architecture, migration process, and key lessons learned.
