Upgrading modules from Drupal 7 to Drupal 8


How do I upgrade my modules from Drupal 7 to Drupal 8. Currently, I am trying to get a module was made for Drupal 7 to work on Drupal 8 so that I can create transitions in pagination (using AJAX). In particular, I want to use this module: https://www.drupal.org/project/views_ajax_fade
However, I haven’t been able to make it work for Drupal 8. I tried using the drupal module updater, but I had an issue with using the commands which weren’t being recognized (in particular, dmu-analyze and dmu-update were not working). Is there any other way to upgrade them (or can somebody quickly update it for me)?

Drupal version:
