# This migrates Traefik from the old path (`/devture-traefik`) to the new path (`/matrix/traefik`, controlled by `devture_traefik_base_path`),
# and from the old hardcoded systemd service name (`devture-traefik.service`) to the new one (`matrix-traefik.service`, controlled by `devture_traefik_identifier`).
#
# Here, we merely disable (and stop) the old systemd service and relocate the data (`/devture-traefik` directory).
# The Traefik role itself (running later) will then ensure this data is up-to-date and will set up the new systemd service.

# It only makes sense to migrate if the identifier or path are different than the default (what we were using before).
