Unplanned shutdown caused process instance migration from old version to newer version was aborted.
The consequence of this abortion make some of the process instances fail to migrate and stuck at the old version. Exception will be throw when you are try to open those process instances from the Inbox. Temporary solution for this known issue is manually correct the data in database with following steps:
1. Check the app_package table to see the "packageVersion" that matches the corresponding "appId" and "appVersion". For example the value could be "10".
2. Update the PDefName to that version (e.g. crm#10#approver_process) for the matching activity "Id" in SHKActivities
update SHKActivities set PDefName = "crm#10#approver_process" where ProcessId in (select id from SHKProcesses where PDefName = "crm#9#approver_process" and State = 1000000)
3. Update the ActivityProcessDefName to that version (e.g. crm#10#approver_process) for the matching activity "Id" in SHKAssignmentsTable
update SHKAssignmentsTable set ActivityProcessDefName = "crm#10#approver_process" where ActivityProcessId in (select id from SHKProcesses where PDefName = "crm#9#approver_process" and State = 1000000)
4. Update the PDefName to that version (e.g. crm#10#approver_process) for processes which failed to update in SHKProcesses table
update SHKProcesses set PDefName = "crm#10#approver_process" where PDefName = "crm#9#approver_process" and State = 1000000
