Error description
When migrating process instances, if the instance being migrated is currently executing on a BPD that does not exist in the target snapshot, runtime and migration errors will occur. The migration to the target snapshot will succeed without any errors. However, when trying to resume the instance, a runtime error will occur. Also, attempting to migrate the instance back to the old snapshot will fail as well with the following exception in the logs: RuntimeServic E SERVER_MIGRATION_FAILURE when migrating BPD with instance ID = BPDInstance.1097 from snapshot Snapshot.bf11bb48-e195-40de-964a-c602940909ec to target snapshot Snapshot.f2e19ff9-1717-4e2f-9afa-008197488184 com.lombardisoftware.core.TeamWorksException: Business Process Diagram with ID BPD.14f4494d-930a-4d36-871a-381138da076d not found. The exception during resuming the instance is expected since runtime cannot find the BPD model to resume from. However, the process instance should be able to migrate back to the old snapshot so the process instance may continue and complete.

Problem summary
ERROR DESCRIPTION - When migrating instances from one snapshot to another, the migration fails due to a missing service or BPD in the source snapshot. The following error may be seen when attempting to migrate: CWLLG0234E: An attempt to get a process instance (id=100,115,502) failed because of an unexpected exception. Error: Service with ID TWProcess.d908445e-2f52-4874-8a37-5ddc5a9fdf1b not found. PRODUCTS AFFECTED IBM Business Process Manager (BPM) Advanced IBM BPM Standard IBM BPM Express LOCAL FIX - None PROBLEM SUMMARY Instance migration will fail if you try to migrate an instance which has a service or BPD that does not exist in the source snapshot. To get into this case scenario, the initial migration of instances to the new snapshot will succeed even when the target snapshot is missing some artifacts. However, when the user tries to migrate these instance back to the initial snapshot, the migration fails as the current snapshot's model does not have the missing artifacts. In this case, the instances are stuck running on the current snapshot and may encounter runtime failures due to the missing artifacts.
