Upgrading to a New NetBox Release

Review the Release Notes

Prior to upgrading your NetBox instance, be sure to carefully review all release notes that have been published since your current version was released. Although the upgrade process typically does not involve additional work, certain releases may introduce breaking or backward-incompatible changes. These are called out in the release notes under the version in which the change went into effect.

!!! note Beginning with version 2.8, NetBox requires Python 3.6 or later.

Install the Latest Code

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.

Option A: Download a Release

Download the latest stable release from GitHub as a tarball or ZIP archive. Extract it to your desired path. In this example, we'll use /opt/netbox.

Download and extract the latest version:

# wget https://github.com/netbox-community/netbox/archive/vX.Y.Z.tar.gz
# tar -xzf vX.Y.Z.tar.gz -C /opt
# cd /opt/
# ln -sfn netbox-X.Y.Z/ netbox

Copy the 'configuration.py' you created when first installing to the new version:

# cp netbox-X.Y.Z/netbox/netbox/configuration.py netbox/netbox/netbox/configuration.py

Also copy the LDAP configuration if using LDAP:

# cp netbox-X.Y.Z/netbox/netbox/ldap_config.py netbox/netbox/netbox/ldap_config.py

Be sure to replicate your uploaded media as well. (The exact action necessary will depend on where you choose to store your media, but in general moving or copying the media directory will suffice.)

# cp -pr netbox-X.Y.Z/netbox/media/ netbox/netbox/

Also make sure to copy over any custom scripts and reports that you've made. Note that if these are stored outside the project root, you will not need to copy them. (Check the SCRIPTS_ROOT and REPORTS_ROOT parameters in the configuration file above if you're unsure.)

# cp -r /opt/netbox-X.Y.Z/netbox/scripts /opt/netbox/netbox/scripts/
# cp -r /opt/netbox-X.Y.Z/netbox/reports /opt/netbox/netbox/reports/

If you followed the original installation guide to set up gunicorn, be sure to copy its configuration as well:

# cp netbox-X.Y.Z/gunicorn.py netbox/gunicorn.py

Option B: Clone the Git Repository

This guide assumes that NetBox is installed at /opt/netbox. Pull down the most recent iteration of the master branch:

# cd /opt/netbox
# git checkout master
# git pull origin master
# git status

Run the Upgrade Script

Once the new code is in place, verify that any optional Python packages required by your deployment (e.g. napalm or django-auth-ldap) are listed in local_requirements.txt. Then, run the upgrade script:

# ./upgrade.sh

This script:

  • Destroys and rebuilds the Python virtual environment
  • Installs all required Python packages (listed in requirements.txt)
  • Installs any additional packages from local_requirements.txt
  • Applies any database migrations that were included in the release
  • Collects all static files to be served by the HTTP service
  • Deletes stale content types from the database
  • Deletes all expired user sessions from the database
  • Clears all cached data to prevent conflicts with the new release

!!! note 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 intentionally modifying the database schema.

Restart the NetBox Services

!!! warning If you are upgrading from an installation that does not use a Python virtual environment, you'll need to update the systemd service files to reference the new Python and gunicorn executables before restarting the services. These are located in /opt/netbox/venv/bin/. See the example service files in /opt/netbox/contrib/ for reference.

Finally, restart the gunicorn and RQ services:

# sudo systemctl restart netbox netbox-rq

!!! note It's possible you are still using supervisord instead of systemd. If so, please see the instructions for migrating to systemd.
