Summary
During roll out of new Workflow definition, the in-progress instances will follow the new workflow design which could cause issues on uncompleted and missed tasks, resulting in broken instances.
As alternate workflow is introduced, this problem will be solved by allowing in-progress workflow instances to be isolated from the latest FAB workflow changes. Old instances in production will continue to use the WF Definition in the point of time it was created. In the same manner, new instances will automatically use the latest workflow definition.
Auto-versioning
Changing the workflow definition automatically increments the WF version.

Traceability
To track back changes in workflow definition, you may use the following field relations:
/IQX/FORMHD_INST-WF_INSTANCE - contains the Hash Characters for WF definition version in which the instance run
Plug in /IQX/FORMHD_INST-WF_INSTANCE to /IQX/FAB_WF-MD5_CHECKSUM to know the version number for said WF definition.
/IQX/FAB_WF-MODIFIED_* fields show changes in WF definition version.
Plug in /IQX/FORMHD_INST-WF_INSTANCE to /IQX/FAB_WF_INST-WF_INSTANCE to know more on the details of current WF definition used.
/IQX/FAB_WF_INST-CREATED_* fields show details of WF Definition creation
