This document discusses migrating Oracle databases to EDB Postgres. It outlines the steps to migrate, including assessing the database, preparing the environment, migrating database objects and data, porting applications, testing, integrating, and rolling out the migration. It then provides two case studies of large companies that migrated from Oracle to EDB Postgres to significantly lower costs while still meeting their business and technical requirements.
