	Non-puppet nodes:
	- Update rolemap.yaml to the new domain names
	- On each host edit /etc/hosts and change the domain
	- Run puppet agent twice on each host

	Renaming puppetdb server:
	- Do the above
	- Restart these services on the puppetdb server in some order (maybe even this one?):
	- postgresql
	- puppetdb
	- uwsgi-puppetdb-microservice
	- nginx
	- Restart apache2 on puppetmaster.

	Renaming puppetmaster:
	- Update rolemap.yaml
	- Edit /etc/hosts and set new domain
	- Run puppet agent. It will fail reloading apache2
	- cp -a /var/lib/puppet/server/ssl/ca/signed/<new fqdn>.pem /var/lib/puppet/server/ssl/certs/
	- cp -a /var/lib/puppet/ssl/private_keys/<new fqdn>.pem /var/lib/puppet/server/ssl/private_keys/
	- restart apache2
	- on each client:
	- sudo sed -i 's/eqiad.wmflabs/eqiad1.wikimedia.cloud/' /etc/puppet/puppet.conf
	- sudo sed -i 's/eqiad.wmflabs/eqiad1.wikimedia.cloud/' /etc/puppet/puppet.conf.d/10-main.conf
	- sudo run-puppet-agent

	Finally:
	- Drop the old hostnames from puppet db: `puppet node deactivate <node>`
	- And remove their certs and other metadata: `puppet node clean <node>`
