Upgrade to Paragon Automation Release 23.1
If your installed version is Paragon Automation Release 21.3, we recommend that you upgrade to Release 22.1 and then upgrade that to Release 23.1.
If your installed version is Paragon Automation Release 21.2, you cannot upgrade to Paragon Automation Release 23.1. You must install Paragon Automation Release 23.1 afresh.
Before You Upgrade:
- Verify that the control host and cluster nodes meet the preparation prerequisites described in Installation Prerequisites on Ubuntu or Installation Prerequisites on CentOS as required.
- (Optional) Back up the config-dir directory on your control host to an alternate directory or to a remote location. The config-dir contains the inventory, config.yml, and id_rsa files for your current Release 22.1 setup. If the upgrade fails, you can reinstall your current setup with the same installation configuration files. See Back Up the Control Host.
- (Optional) Back up your current Release 22.1 configuration. If the upgrade fails, you can restore your current deployment from the backed-up configuration. See Back Up the Configuration.
Upgrade from Release 22.1 to Release 23.1
Upgrade Failure Scenario
If upgrade fails and you are unable to install Release 23.1, you must reinstall Release 22.1 to restore operations. Use one or both of the following options to restore the cluster.
-
You can use the backed-up config-dir files to reinstall the previously operational cluster.
-
You can restore the cluster data if you previously backed up Release 22.1 configuration.

-
Back up the Release 22.1.0-SP2 configuration.
-
Upgrade the Release 22.1.0-SP2 cluster to Release 23.1.
