Environment Upgrade Order

If you have a development environment, you must upgrade it first. During this phase, your customizations are merged with the new Siebel release. A merged repository file and database schema file are created and become inputs to the production test environment upgrade and production upgrade.

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