Error description
When you migrate instances from one snapshot to a newer one, instances might fail to migrate to the new snapshot. In an FFDC log, you see an error similar to this error: Caused by: com.lombardisoftware.core.TeamWorksRuntimeException: Attempt to access TWObject with classId TWClass.ab704972-f8ab-4233-a192-23836c181300 that is not available vc=Snapshot.1acfg651-ee70-4aaa-8af8-5f0ebf8fe9d0 at com.lombardisoftware.core.TWObject.getActiveForm (TWObject.java:1497) at com.lombardisoftware.core.TWObject.getType (TWObject.java:536) at com.lombardisoftware.bpd.runtime.engine.st.

Local fix
Problem summary
When you migrate instances to a new snapshot, new variables that you added with a default value are automatically initialized. While going through the values that are set in the business process definition (BPD) instance, IBM BPM tries to look up the business object definition in the new snapshot where the variable was removed, causing the error.
Problem conclusion
A fix will be included in an IBM BPM V8.5.6.0 cumulative fix that ensures variables that were deleted are ignored.
