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.
The below sub-sections describe some key changes that deployers should be aware of, but are not intended to be a replacement for reading the release notes carefully and in depth.
Updating from Nautobot 1.0.x to 1.1.x¶
Migration from RQ to Celery¶
Prior to version 1.1.0, Nautobot utilized RQ as the primary background task worker. As of Nautobot 1.1.0, RQ is now deprecated, as Celery has been introduced to eventually replace RQ for executing background tasks within Nautobot. All Nautobot core usage of RQ has been migrated to use Celery.
RQ support for custom tasks was not removed in order to give plugin authors time to migrate, however, to continue to utilize advanced Nautobot features such as Git repository synchronization, webhooks, jobs, etc. you must migrate your
nautobot-worker deployment from RQ to Celery.
Please see the section on migrating to Celery from RQ for more information on how to easily migrate your deployment.
Updating from Nautobot 1.1.x to 1.2.x¶
Introduction of Celery Beat Scheduler¶
As of Nautobot v1.2.0, Nautobot supports deferring ("scheduling") Jobs. To facilitate this, a new service called
celery-scheduler is now required. Please review the service installation documentation to find out how to set it up.
Update Prerequisites to Required Versions¶
Nautobot v1.0.0 and later requires the following:
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.
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).
Unless explicitly stated, all steps requiring the use of
nautobot-server in this document should be performed as the
Upgrade Nautobot using
$ 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.
django-auth-ldap) are listed in
Then, upgrade your dependencies using
$ 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 web and background services:
$ sudo systemctl restart nautobot nautobot-worker nautobot-scheduler
