MongoDB how to update duplicates and insert new documents at the same time?

Question

MongoDB

Every hour, an array of objects comes in, in which most of the duplicates and 20 percent of the new values.
The task is that, it is necessary to interpose all this array of documents into a database. Update duplicates, insert new values.
Used this approach:

postsModel.insertMany(result, (err, posts) => {
          if (err) {
            Logs.info(err);
          } else {
            Logs.info("Success!");
          }
        });

Exceptions... , adds the first (new) documents, nothing happens after that.
