Version upgrades#

Updates to Endpoint Analytics may add new features, enhance existing functionality, and/or apply security patches to address emerging threats.

This section covers the installation process for update packages as well as additional recommendations for pre-upgrade preparations.

Note

All update packages are extensively tested by the Plixer team before they are made available. For assistance with the update process and other concerns, contact Plixer Technical Support.

Update preparations#

Before attempting to install any type of update package, the following procedures should be observed:

  1. Verify that the version currently installed can be upgraded to the target version.

  2. Confirm that a recent backup has been saved or manually back up the database from the System Summary page. The backup file should also be copied to an external location.

  3. Verify that the current license key(s) will remain valid after the upgrade.

  4. Delete any older update files/packages from the home directory for the beacon user.

Update installation#

Follow the steps below to update the current Endpoint Analytics instance to the latest version:

  1. Ensure that a backup of the current install has been saved to an external location, as part of the recommended preparatory procedures.

  2. SSH to the Endpoint Analytics instance as the beacon user and start a new tmux session:

    tmux new -s upgrade

  3. Download the update package for the latest version (will be saved in the format pea_VERSION_upgrade.tar.gz):

    curl https://files.plixer.com/PlixerEndpointAnalyticsUpgrade.tar.gz

  4. Extract the contents of the downloaded file to the same (home) directory:

    sudo tar -xvzf pea_VERSION_upgrade.tar.gz

  5. Navigate to the extracted directory, and then set the correct permissions for the update script:

    cd pea_VERSION_upgrade/ 
sudo chmod 755 upgrade.sh

  6. Run the update script, and then type yes when prompted:

    sudo ./upgrade.sh

Once the script completes running and the system reboots, the instance will be running the latest version of Endpoint Analytics.

Offline updates#

To update an Endpoint Analytics instance that cannot access the Internet, follow these steps:

  1. Download the update package from a system with access to the Internet.

  2. Copy the package to the home directory of the beacon user.

  3. Follow the online update procedure above starting from step 4.

Once the script completes running and the system reboots, the instance will be running the latest version of Endpoint Analytics.
