Runtime process migration is the transfer of a running process instance from one workflow engine to another. The transfer includes the process description, its state information (i.e. process state, activity states and variable values), and associated log data. Process runtime migration can be applied in order to enable the continuous execution of a process instance in a different environment, e.g. for QoS optimization, load-balancing or if required resources are locally unavailable.

Scenarios
- WINERY-S-1: Collaborative Transport Chain Control. When noticing a deviation of the measured values from the estimated range (malfunction), a predefined process reacts to the situation. While due to performance restrictions wireless sensors are not able to execute the process itself, already existing devices and resources in the mobile vicinity should support the execution of the process [PO-IA-3.2.1].
