When a release definition is created, the generic process rules are used to define how the specific process rules for that release are formed. The resultant release specific process rules are then used for controlling the process for that release and what changes are included when a project or project grouping for that release is updated. The release definition and the set of process rules it uses defines the valid purposes that may be used for the release and how a project or project grouping with that release and one of those valid purposes is updated.
If release definitions are not excluded from a transfer set, then release definitions that are included in the releases part of a transfer package are imported.
