When installing a process application snapshot with new version of a BPEL process, the integration developer may need the latest process version to be applied to the new process instances and to process instances that have already started. To migrate all running BPEL process instances to a new version of the process, the integration developer can:
select 'Delete' which will delete running instances and start new again.
select 'Migrate' which will migrate running instances to the new snapshot.
use Business Process Choreographer Explorer to migrate running instances.
use an administrative script (migrateProcessInstances.py) to migrate running instances.
