Universal Agent 1.0.1 is a minor release that only affects the UA Manager. There is no need to redeploy the UA clients deployed in each endpoint when upgrading from V1.0.0 to V1.0.1

UA Manager V1.0 → V1.0.1 upgrade procedure

The upgrade process will overwrite some existing folders in the UA Manager filesystem. Make sure you back up the folders indicated in the instructions below.

Back up your existing devo-ua-deployer folder. If you used one of the existing example inventory files (e.g., py3-1host-example.yaml) make sure to have a copy at hand so you can use it during the upgrade process.
Back up your existing /etc/devo-ua-manager folder.
Download the new package and copy in the same directory level where the existing devo_ua_deployer folder is listed.
Untar the downloaded package so that it overrides the contents of the existing devo_ua_deployer folder.
Make sure that your inventory file still exists in $HOME/devo-ua-deployer/inventories and that it still applies to your environment.
a. If your inventory file is not there or it has been overwritten, copy the existing inventory file from the backup folder created in step 1.
b. Check that the Devo domain certificates are still in place in $HOME/devo-ua-deployer/domain-certs.
Verify any configuration changes applied to the baseline configuration (e.g., enabled/disabled packs) and check whether those need to continue to be applied after the upgrade. Both packs and configurations will be updated as part of the platform upgrade process, so they might be lost after the installation is completed. If there are specific changes in the centralized configuration (options.yaml), those changes need to be merged before running the playbook. If you want to keep those changes applied, please contact Devo to get specific support for that migration.
Run universal-agent playbook using the following command (replace your_inventory.yaml for the actual name of your inventory file): ansible-playbook -i inventories/your_inventory.yaml playbooks/devo-universal-agent.yaml.

Post-installation steps

Check that the UA manager interface is accessible.
Check that all the packs and queries are available:
a. The default packs are installed in ENABLED state. If you want to disable any of them, simply deactivate them via the administration web UI.
b. Any other additional packs should continue being available.
Check that the data collected from the endpoints flows into Devo after the installation.

UA Manager rollback procedure

In the unlikely event of the UA Manager node ending up in a faulty status after an upgrade process, apply the following rollback procedure:

1. Restore your original devo-ua-deployer folder from the backup location.

2. Connect to all manager hosts and ensure duam-fleet is purged (choose the right one for your linux distro):

sudo systemctl apt remove -f duam-fleet

or

sudo yum remove -f duam-fleet

3. Ensure packs are removed. This step is required only on the first duam-manager host.

sudo rm -f /var/devo-ua-manager/packs

4. Change the current directory to $HOME/devo-ua-deployer and run the following command (replace your_inventory.yaml for the actual name of your inventory file): ansible-playbook -i inventories/your_inventory.yaml playbooks/devo-universal-agent.yaml
