Case Study: Leading U.S. Wireless Carrier Saves Millions by Migrating 100TB from Oracle to EDB Postgres with EnterpriseDB

U.S. Wireless Carrier Migrates 100TB Oracle Database to EDB Postgres in First Open Source Initiative

A large regional U.S. wireless carrier faced industry pressure to modernize operations, reduce vendor lock-in, and lower operating expenses while improving customer experience. As its first open‑source initiative it selected a 100 TB, mission‑critical Oracle Exadata application (storing geospatial, device and user data, plus voice recordings) as the migration candidate to gain greater infrastructure efficiency and flexibility.

EnterpriseDB managed a two‑week migration to the EDB Postgres Platform with Cloudera, using Postgres enhancements (partitioning, heterogeneous links) and data adaptors to integrate structured and unstructured data and tie into existing HPE storage and backup. The move cut operating costs by several million dollars, delivered faster analytics and stronger control over mixed data, and freed budget and flexibility for new data‑driven applications and customer‑experience initiatives.
