If you have custom `matrix_riot_web_` variables in your `inventory/host_vars/matrix.example.com/vars.yml` file, you'll need to rename them (`matrix_riot_web_` -> `matrix_client_element_`).
Some other playbook variables (but not all) with `riot` in their name are also renamed. The playbook checks and warns if you are using the old name for some commonly used ones.
- (**avoiding changes** - using the old `riot.example.com` domain and avoiding DNS changes) -- to keep using `riot.example.com` instead of `element.example.com`, override the domain at which the playbook serves Element: `matrix_server_fqn_element: "riot.{{ matrix_domain }}"`
- (**embracing changes** - using only `element.example.com`) - set up the `element.example.com` DNS record (see [Configuring DNS](configuring-dns.md)). You can drop the `riot.example.com` in this case.
