 - (**avoiding changes** - using the old `riot.DOMAIN` domain and avoiding DNS changes) -- to keep using `riot.DOMAIN` instead of `element.DOMAIN`, override the domain at which the playbook serves Element: `matrix_server_fqn_element: "riot.{{ matrix_domain }}"`
 
-- (**embracing changes** - using only `element.DOMAIN`) - set up the `element.DOMAIN` DNS record (see [Configuring DNS](configuring-dns.md)). You can drop the `riot.DOMAIN` in this case. If so, you may also wish to remove old SSL certificates (`rm -rf /matrix/ssl/config/live/riot.DOMAIN`), so that `certbot` would stop trying to renew them.
