Upgrading an onsite deployment to a new release

VisibleThread product upgrades are shipped as upgrade files with the extension '.tar.gz', for example  Upgrade-2.14-build-2168.tar.gz

Download details for each upgrade are emailed to all VisibleThread customers as soon as the upgrade becomes available. If you are missing details of where to retrieve an upgrade please contact our support team.

When you have downloaded your upgrade file, it needs to be added to the /home/visiblethread/VisibleThreadTools/upgrade folder on the VisibleThread Virtual Appliance.

Uploading the upgrade file to the Virtual Appliance

You can upload the upgrade file to the Virtual Appliance via SSH (Secure SHell) using port 22. The easiest way to do this is to use one of a number of freely available tools such as the FileZilla client ( or WinSCP ( The next section outlines the detailed steps to complete this:

  • Connect to your Virtual Appliance using the following details:
    • IP address: The IP Address of your Virtual Apppliance/VisibleThread Server.
    • username: visiblethread
    • Password: password (unless changed when completing deploying the VisibleThread server)
    • Port: 22
  • Once connected navigate to the /home/visiblethread/VisibleThreadTools/upgrade folder.
  • Upload the upgrade file to this folder.

Applying the upgrade to the Virtual Appliance

Note: Applying the upgrade will bring down the VisibleThread application for several minutes.

The VisibleThread Virtual Appliance contains an upgrade script that will perform an upgrade of the Virtual Appliance. To run this script log on to the VisibleThread Virtual Appliance console and execute the following commands:

cd /home/visiblethread/VisibleThreadTools
screen ./ upgrade/<upgradefilename.tar.gz>


Note: You may be prompted for the "visiblethread" user password when running this command. This will unpack the archive, deploy the upgrade files and restart the application.

Testing the upgrade

To verify the upgrade was performed successfully, point your browser at https://<VisibleThreadServerAddress> and verify the version number (e.g. 2.14) on the sign-in screen looks like the one below
