About Siebel Upgrade Environments

There are three Siebel database environments: Development, Test, and Production. If you have a development environment, then you must upgrade it 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 will perform after completing the development environment upgrade.

If you do not have a development environment, or have not customized your repository, then no repository merge is required. You can use the repository and schema definition files included in the new release to upgrade your test environment and production environment.

The production environment contains only the Runtime Repository and the required Design Time Repository. The production repository is extracted during the development upgrade.
