About Siebel Upgrade Environments

There are three Siebel database environments: Development, Test, and Production. You must upgrade your development environment first. When you upgrade your development environment, your previous customizations are merged with the new release.

The newly merged repository and schema definitions then become inputs to the test environment upgrade and production upgrades which you'll perform after completing the development environment upgrade.

Note: A development environment is required to run modern versions of Siebel CRM. If you didn't previously have a development environment, you'll need to create one.

Please contact Oracle's Customer Success Services (CSS) for assistance in creating one.
