With the next upcoming version of Imixs-Workflow 5.1.10 we will introduce the new Multi-Model Support. With this function, a long-running business process can easily be distributed into separate model files without having to split up a running process instance or create a new sub-process. This will make modeling much easier and clearer.
In difference to the the already existing feature of the Split Events, the model version can be changed within a running process instance by simply adding a link-event:

The outgoing event describes the new model version in the workflow result definition:
<model>
<version>approval-model-1.0.0</version>
<event>42</event>
</model>
The Imixs-Workflow engine will execute the new event immediately within the new model and automatically assigns the already running process instance. The consistency of the process will be guarantied by the Imixs-Workflow Kernel.
This modeling approach is particularly interesting for long-running, complex business processes with multi-stage approval procedures because it significantly increases the maintainability and overview in such models.
