Stop any currently running environments
Run den svc down -v to stop and remove the Den service images
Uninstall Den
If on a Mac or Linux machine update /etc/ssh/ssh_config and remove everything between the WARDEN START and WARDEN END headers
Upgrade/Install Warden
Run warden install
Run warden sign-certificate for in each environment before the first time you start it
