Business Process Server supports sequential versioning, where the different versions of a process template share the same Application Name, which is the name of the installed process template. Therefore, while versioning, you should follow this convention of naming the process templates:
All process templates have a common application name (AppName) defined or inherited. Typically, it indicates the objective of the application.
Each version of the process template is named as (AppName) _v (version ID).
For example, if the AppName is "Approval", then the first version should be named "Approval_v1", and the third version should be named "Approval_v3". These names are displayed in Progress Developer Studio for OpenEdge, and Business Process Portal.
