How do I know that my Production configuration is identical to my signed-off UAT configuration?

As an Oracle User, how do I know that my Production configuration is identical to my signed-off UAT configuration?

Rapid4Cloud's comparison report will highlight the differences between 2 or more Oracle environments, so you can know immediately whether Production matches the signed off configuration. You can also run a report on Production at go-live time and use this as the "gold standard" snapshot.
