Description
During process instance migration, MigrationManager tries to find "upgradedNode" which meets UniqueId of old node. If upgradedNode is not found and NodeMapping is not provided, finally MigrationManager leaves the old nodeInstance as is.
It will result in an issue after migration.
If the node order in BPMN2 file has changed, the old nodeInstance will connected to a different node. For example, nodeInstance of HumanTaskNode may connected to EndNode so result in ClassCastException.

Shouldn't MigrationManager do fail-fast in this case?
