Viewing valid CEV upgrade targets for RDS Custom for Oracle DB instances

You can see existing CEVs on the Custom engine versions page in the AWS Management Console.

You can also use the describe-db-engine-versions AWS CLI command to find valid CEVs to use when you upgrade your DB instances, as shown in the following example. This example assumes that you created a DB instance using the engine version 19.my_cev1, and that the upgrade versions 19.my_cev2 and 19.my_cev exist.

aws rds describe-db-engine-versions --engine custom-oracle-ee --engine-version 19.my_cev1

The output resembles the following. The ImageId field shows the AMI ID.
