Oracle Database Migration to Aurora MySQL using Oracle Database Gateways

The article discusses the process of migrating Oracle Database to Aurora MySQL using Oracle Database Gateways. The main reason for migration is to reduce licensing costs, modernize to cloud-native architecture, and enable more flexible data usage with microservices architecture. The recommended method for migration is to use AWS Database Migration Service (AWS DMS) for Amazon Aurora MySQL or Amazon Relational Database Service (RDS) for MySQL. However, AWS DMS may not support all special cases due to source and target database-specific characteristics. In such cases, Oracle Database Gateways can be used to create database links between Oracle Database and MySQL database, allowing for migration of data from Oracle to MySQL.
