Upgrading an on-premise VT Writer deployment

This article contains instructions for upgrading an on-prem VT Writer Deployment to a newer release.

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 mail support@visiblethread.com.

Red Hat and Ubuntu (virtual appliance) deployments each have a different upgrade mechanism. Each one will be covered below.

Note: Before upgrading, we recommend that you perform a data backup, in the event that the upgrade encounters any unforeseen issues. To do so, follow the steps outlined here https://support.visiblethread.com/hc/en-us/articles/360025227351

 

Upgrading a VT Writer Ubuntu deployment

Ubuntu upgrade files have an extension of ‘.tar.gz’ so an example file might be ‘ReadabilityUpgrade2.4.4.tar.gz’.

When you have downloaded your upgrade file, it needs to be added to the /home/visiblethread/VisibleThreadTools/upgrades folders 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 (http://filezillaproject.org/) or WinSCP (http://www.winscp.net). The next section outlines the detailed steps to complete this:

  1. Connect to your Virtual Appliance using the following details:
    • IP address
    • Username: visiblethread – Password: password (unless changed)
    • Port: 22
  2. Once connected, navigate to the /home/visiblethread/VisibleThreadTools/upgrades folder.
  3. Upload the upgrade file to this folder. 

Applying the upgrade to the Virtual Appliance

The VT Writer server contains an upgrade script that will perform an upgrade of the application. 
To run this script, log on to the server console and execute the following commands:


cd /home/visiblethread/VisibleThreadTools
sudo ./vt-upgrade.sh upgrades/<upgradefilename.tar.gz>

Note: You may be prompted for the “visiblethread” user password when running this command.
This will extract the archive, deploy the release files and restart the application.

Verifying the upgrade is successful

To verify the upgrade was successful take the following steps:

  1. Ensure the version for each of the following (run the commands below) matches the VT API version in your upgrade email e.g. "the latest version of the VT API is 0.24":
  • dpkg -s vtapi-doc-worker
  • dpkg -s vtapi-web-worker
  • dpkg -s vtapi-scan-worker
  1.  

  2. Go to the VT Writer application in your browser, and verify the version number matches the version in the subject line of your upgrade email e.g. "VT Writer 2.6.1 Upgrade". The version number should be displayed on the login screen.
  3. Sign in to the VT Writer application and upload a document for analysis, verify the analysis completes.
  4. If you are using the Email service send an email with a document attached (Word or PDF document) to the email address you have designated for readability scans.
  5. Verify you get a response with the document analysis results.

The upgrade process generates a log file in the following location:

 /home/visiblethread/VisibleThreadTools/upgradelog.txt 

You should send this file to support@visiblethread.com and they will verify that the upgrade was successful.

 

Upgrading a VT Writer Red Hat deployment

Upgrades are distributed in the form of new rpm packages. You will have been provided details of where to download the upgrade from VisibleThread support via e-mail. Mail support@visiblethread.com if you have not received these details.

Download the new .rpm files to your Red Hat server, and then install them :

yum install -y visiblethread-api-X.Y.Z.rpm
yum install -y visiblethread-readability-X.Y.Z.rpm

Verifying the upgrade is successful

To verify the upgrade was successful:

  1. Check the version of the visiblethread packages using yum. Ensure the visiblethread-api version number matches the VT API version in your upgrade email e.g. "the latest version of the VT API is 0.24". Ensure that the visiblethread-readability version number matches the subject line of your upgrade email e.g. "VT Writer 2.6.1 Upgrade". 
  • yum info visiblethread-api 

    yum info visiblethread-readability
  1.  

  2. Go to the VT Writer application in your browser, and verify the version number matches the version in the subject line of your upgrade email e.g. "VT Writer 2.6.1 Upgrade". The version number should be displayed on the login screen.
  3. Sign in to the VT Writer application and upload a document for analysis, verify the analysis completes.
  4. If you are using the Email service send an email with a document attached (Word or PDF document) to the email address you have designated for readability scans.
  5. Verify you get a response with the document analysis results.
