Oracle Database Enterprise Edition (EE) is a popular choice for running applications in many enterprises. In some cases, however, applications use few or no Oracle Database EE features, so there is a lack of justification for incurring huge licensing costs. You can achieve cost savings by downgrading such databases to Oracle Database Standard Edition 2 (SE2) when you migrate to Amazon RDS.
This pattern describes how to downgrade from Oracle Database EE to Oracle Database SE2 when migrating from on premises to Amazon RDS for Oracle. The steps presented in this pattern also apply if your EE Oracle database is already running on Amazon RDS or on an Amazon Elastic Compute Cloud (Amazon EC2) instance.
For more information, see the AWS Prescriptive Guidance guide on how to Evaluate downgrading Oracle databases to Standard Edition 2 on AWS.
