This migration pattern provides step-by-step guidance for migrating an Amazon Relational Database Service (Amazon RDS) for Oracle database instance to an Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition database by modifying the aws_oracle_ext and orafce extensions to PostgreSQL (psql) native built-in code. This will save processing time.
The pattern describes an offline manual migration strategy with no downtime for a multi-terabyte Oracle source database with a high number of transactions.
