I'm looking for answers too and the best switcheroo I've found so far is
http://dokku.viewdocs.io/dokku/deployment/zero-downtime-deploys/ which
leverages Docker and it's not at all integrated with systemd.

Guess a systemd integrated solution would be leveraging machinectl,
journalctl and more powerful service control, but I haven't seen an
orchestrated deployment like that yet. Maybe CoreOS has something, I am
not sure.
