      Riot has been renamed to Element (https://element.io/blog/welcome-to-element/).
      The playbook will migrate your existing configuration and data automatically, but you need to adjust variable names.
      Please change your configuration (vars.yml) to rename all riot-web variables (`{{ item.old }}` -> `{{ item.new }}`).
      Also note that DNS configuration changes may be necessary.
