Not able to cast old Immunization datatype to new Immunization datatype

Question

As new datatype is introduced for Immunization, I am not able to convert/cast the old Immuniations to new datatype or viceversa. Below code stopped working for me:

            // create and add the filter

            HealthRecordFilter filter = new HealthRecordFilter();

            filter.TypeIds.Add(new Guid(ImmunizationGUID));

            filter.TypeIds.Add(Microsoft.Health.ItemTypes.Immunization.TypeId);

            filter.View.Sections = HealthRecordItemSections.All;

            searcher.Filters.Add(filter);

            HealthRecordItemCollection hvItems = searcher.GetMatchingItems()[0];

            foreach (HealthRecordItem item in hvItems)

            {

                Microsoft.Health.ItemTypes.Immunization hvImm = item as Microsoft.Health.ItemTypes.Immunization;

            }

Here, for the new Immunization datatypes, it is working fine, but it turns out to be NULL for the old ones. Any way to covert it?
