Migrating from Oracle EE to SE on AWS RDS

There isn’t an easy way to do an in-place conversion from Oracle EE database to SE. This is true whether the database is on RDS, on premise, or running on EC2. This is because Oracle EE supports many different options that are not available in Oracle SE. Therefore, exporting and importing would be the only way to do it.

Oracle licensing on AWS

Oracle licenses portability and support on AWS is a bit different between Oracle on EC2 and Oracle on RDS.  However, with both models you can Bring Your Own Licenses (BYOL). With RDS, you have the option of BYOL (Bring Your Own License) or License Included.  With Oracle on EC2, you can only BYOL. All Oracle licenses are portable to AWS as indicated here: http://aws.amazon.com/oracle/.   More details on how your Oracle licenses work on AWS can be found here: http://www.oracle.com/us/corporate/pricing/cloud-licensing-070579.pdf.  The Oracle FAQ has more details on working with Oracle on AWS: http://www.oracle.com/technetwork/topics/cloud/faq-098970.html#Oracle_AWS.
