Deploying a new version of the Project

You can run multiple versions of the same Project on different StreamServer applications in the same application domain. For example, to preview and release paused Messages based on the original version of the Project, and at the same time create new documents based on the updated version of the same Project.

To avoid versioning conflicts, you must never simultaneously run different versions of a Project, with the same version of a template, on different StreamServer applications in the same application domain.

Increase the Project version

To deploy a new Project version, you must manually increase the Project version at export. When you increase the Project version, the versions of all included StoryTeller templates are automatically increased. When the StreamServer application is started, all Composition Center document definitions based on the templates are automatically unpublished.

Note:

If there is a large amount of document definitions based on the StoryTeller templates, the template synchronization process takes quite some time. We recommend that the Composition Center application is not accessed during this process.

Impact control on application domain level

At the deployment, Control Center compares the Project and template versions to the ones already deployed in the application domain. If you try to deploy a combination of Project and template versions that is not compatible with the versions already deployed, a warning is issued. For example, if you revert to an earlier version of a template in a later version of the Project.

To avoid versioning conflicts, you must never deploy an unsupported combination of Project and template versions.

Only one published version of a document definition at a time

After deployment and template synchronization, all document definitions based on the templates are automatically unpublished in Composition Center. When the business user republishes a document definition, the document definition is tied to the StreamServer application that runs the latest Project version. This StreamServer application is the only one that can create new documents based on the document definition.

To deploy a new version of the Project

1	In Design Center, when you export the modified Project or create a release for the modified Project, increase the Version number.

2	In Control Center, create a new StreamServer application.

3	Deploy the export file for the modified Project to the StreamServer application. See Deploying a Design Center Project in the Control Center documentation.
