CWTKA0145E The task instance ''0'' cannot be migrated to the specified template ''1''.
Explanation
Because the task instance was created dynamically at runtime, it does not have a corresponding task template, and therefore cannot be migrated to have a new corresponding task template.
User response
Try one of the following actions: In your runtime client, jump to an activity in the process that is before the specified task instance, and retry the migration. Remove the task template for the task instance, and try to migrate the process instance to the new template.
