Fortunately, they will still earn promotion points. However, you must complete the entire correspondence course and possess a certificate of completion in order to get the points. Sub-courses on their own will not count for promotion points. I suggest you take a look at your course history on the ATIA website to see how many full courses you have actually completed and determine how many points you will have under the new ststem.
