When the requirements change, you may need to create a version ACME_Process_Ver2 for the existing process template, without removing ACME_Process_Ver1. This can be accomplished with the help of API provided by the ProcessTemplate SVO.
public ProcessTemplate createVersion(String xmlFileName)
The following scenarios explain the versioning in more detail:
You can remove the parent process template, which is deprecated, only when all its existing process instances are completed.
If you change the AppName of the latest active version, then the new AppName is reflected on all the versions.
If you remove the latest (active) version, then you can resume any of the deprecated versions.
Note: Versioning does not allow you to activate multiple versions simultaneously.
