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 release in which the change went into effect.

Update Dependencies to Required Versions

NetBox v3.0 and later requires the following:

Dependency Minimum Version
Python 3.7
PostgreSQL 9.6
Redis 4.0

Install the Latest Release

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
sudo tar -xzf vX.Y.Z.tar.gz -C /opt
sudo ln -sfn /opt/netbox-X.Y.Z/ /opt/netbox

Copy local_requirements.txt, configuration.py, and ldap_config.py (if present) from the current installation to the new version:

sudo cp /opt/netbox-X.Y.Z/local_requirements.txt /opt/netbox/
sudo cp /opt/netbox-X.Y.Z/netbox/netbox/configuration.py /opt/netbox/netbox/netbox/
sudo cp /opt/netbox-X.Y.Z/netbox/netbox/ldap_config.py /opt/netbox/netbox/netbox/

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.)

sudo cp -pr /opt/netbox-X.Y.Z/netbox/media/ /opt/netbox/netbox/

Also make sure to copy or link 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.)

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

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

sudo cp /opt/netbox-X.Y.Z/gunicorn.py /opt/netbox/

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
sudo git checkout master
sudo git pull origin master

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:

sudo ./upgrade.sh

Warning

If the default version of Python is not at least 3.7, you'll need to pass the path to a supported Python version as an environment variable when calling the upgrade script. For example:

sudo PYTHON=/usr/bin/python3.7 ./upgrade.sh

This script performs the following actions:

  • 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
  • Builds the documentation locally (for offline use)
  • 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

Note

If the upgrade script prompts a warning about unreflected database migrations, this indicates that some change has been made to your local codebase and should be investigated. 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 (any release prior to v2.7.9), 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

Verify Housekeeping Scheduling

If upgrading from a release prior to NetBox v3.0, check that a cron task (or similar scheduled process) has been configured to run NetBox's nightly housekeeping command. A shell script which invokes this command is included at contrib/netbox-housekeeping.sh. It can be linked from your system's daily cron task directory, or included within the crontab directly. (If NetBox has been installed in a nonstandard path, be sure to update the system paths within this script first.)

sudo ln -s /opt/netbox/contrib/netbox-housekeeping.sh /etc/cron.daily/netbox-housekeeping

See the housekeeping documentation for further details.
