When upgrading to a new version of Mothership all configuration and runtime files are kept in two directories:
config_files- Contains all users and passwords, any TLS certificates and configuration files.
runtime_files- All the runtime data (images, NaCls, uplinks, logs) used by Mothership.
When stopping the Mothership make sure these two directories are kept intact.
Start with pulling the changes from GitHub. This can be done with:
$ git pull
or if you were using a specific ssh key:
$ ssh-agent bash -c 'ssh-add mothership_beta.key; git pull'
To start Mothership with the new version use the same command as referenced in :ref:`Launch command <build_launch_mothership>`.
If Docker is in use make sure the Docker container is rebuilt before launching the new Mothership. See :ref:`mothership-in-docker`
