Upgrading JupyterHub and its database

From time to time, you may wish to upgrade JupyterHub to take advantage of new releases. While much of this process is automated using scripts, such as those generated by alembic for database upgrades, it's critical to backup data and configurations before shutting down the JupyterHub process and server.

Four fundamental steps are needed when upgrading JupyterHub and its database:

  1. Backup
  2. Shutdown
  3. Upgrade JupyterHub
  4. Run jupyterhub upgrade-db to upgrade the database

Let's take a closer look at each step in the upgrade process.
