Upgrading to a New Nautobot Release¶
Review the Release Notes¶
Prior to upgrading your Nautobot 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 Prerequisites to Required Versions¶
Nautobot v1.0.0 and later requires the following:
Dependency | Minimum Version |
---|---|
Python | 3.6 |
PostgreSQL | 9.6 |
Redis | 4.0 |
Nautobot v1.1.0 and later can optionally support the following:
Nautobot v1.1.0 added support for MySQL 8.0 as a database backend as an alternative to PostgreSQL.
Dependency | Minimum Version |
---|---|
MySQL | 8.0 |
Tip
If you wish to migrate from PostgreSQL to MySQL, we recommend creating a new Nautobot installation based on MySQL and then migrating the database contents to the new installation, rather than attempting an in-place upgrade or migration.
Install the Latest Release¶
As with the initial installation, you can upgrade Nautobot by installing the Python package directly from the Python Package Index (PyPI).
Warning
Unless explicitly stated, all steps requiring the use of pip3
or nautobot-server
in this document should be performed as the nautobot
user!
Upgrade Nautobot using pip3
:
$ pip3 install --upgrade nautobot
Upgrade your Optional Dependencies¶
If you do not have any optional dependencies, you may skip this step.
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, upgrade your dependencies using pip3
:
$ pip3 install --upgrade -r $NAUTOBOT_ROOT/local_requirements.txt
Run the Post Upgrade Operations¶
Finally, run Nautobot's post_upgrade
management command:
$ nautobot-server post_upgrade
This command performs the following actions:
- Applies any database migrations that were included in the release
- Generates any missing cable paths among all cable termination objects in the database
- 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
Restart the Nautobot Services¶
Finally, with root permissions, restart the WSGI and RQ services:
$ sudo systemctl restart nautobot nautobot-worker
