Demoting moves items downwards through the Global Stage Lifecycle (GSL).
If an associated deployment area for the project or stream has the Deploy by Default option set, and you have selected the Perform deployment option, the deployment will occur automatically upon demotion; you do not need to have the Deploy privilege. If there are other deployment areas associated with the project or stream, you can also deploy to those areas if you have the necessary privilege.
You can demote through more than one stage in the GSL in the same operation.
