To install a new version of an application, you must first suspend the previous version of the application before installing the new version. For more information about suspending and resuming applications, see the Business Process Portal Administrator’s Guide.
Alternatively, you can invoke the suspend () method in the Process Template SVO in the BP Server API to suspend an installed process template. If you use the createVersion method, then this is done internally.
Note: When you suspend a process template using the suspend() method in the Process Template SVO, you cannot create new instances on the process template. If instances of an already suspended process template require creation, then use the resume() method in the process template SVO for that purpose.
