Change TLD permanently?

Hello!

I have a client that’s decided to switch from a country specific TLD to a more general one (.com). I’m curious what the most preferred way to achieve this would be?

Current setup in wordpress_sites.yml:

site_hosts:
  - canonical: site.se
    redirects:
      - www.site.se

Should I change it into

site_hosts:
  - canonical: site.com
    redirects:
      - www.site.com
  - canonical: site.se
    redirects:
      - www.site.se

or is this more fitting?

site_hosts:
  - canonical: site.com
    redirects:
      - www.site.com
      - site.se
      - www.site.se
