As with the initial installation, you can upgrade NetBox by either downloading the latest release package or by cloning the `master` branch of the git repository.
Download the [latest stable release](https://github.com/digitalocean/netbox/releases) from GitHub as a tarball or ZIP archive. Extract it to your desired path. In this example, we'll use `/opt/netbox`.
It's possible that the upgrade script will display a notice warning of unreflected database migrations:
Your models have changes that are not yet reflected in a migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
This may occur due to semantic differences in environment, and can be safely ignored. Never attempt to create new migrations unless you are inentionally modifying the database schema.
