Upgrading to a new software version

Introduction

This procedure describes the process of upgrading the TruView.  You ony need to upgrade the TruView Central (TVC) via the WebUI with a single file.  The other components of the TruView system, like the TruView Packet (TVP) and the Truview Flow (TVF), will get their embedded software from the TVC automatically when restarting at the end of the upgrade process.  This is true for TruView appliances (TVA) as well as for distributed systems (TVC+TVP+TVF).

Solution

Download

Download the latest software release from the Netscout repository.  Contact TAC if needed.  You should find a single file with a *.tar.gz extension and the release notes.  Download both files (DON'T unzip) and store them in a local file on your computer.

Login

Login to the portal with administrator priviledges and go to the Administration Section by clicking the gear icon in the upper right corner of the screen.

Backup

Before continuing, make a backup of your configuration. 

Read

Read the release notes carefully to see if your system meets the criteria for immediate upgrade to the desired release.  In some rare cases, you may have to upgrade to an intermediate release before you can upgrade to the most recent release.  If that's the case, wait for at least one hour between upgrades. 

Upgrade

Select Software Upgrade from the menu on the left. You mat have to expand the Admin section by clicking on the triangle to the left. The SOFTWARE VERSION popup will apear, showing the current installed version:

Click Browse and point to the *.tar.gz file you've downloaded in step one. Read the warning message and press Yes to continue or No to terminate the update process:

Click Install and witness the upload of the software:

Once the upload is complete, you will be logged out from the portal.  You see this message on the portal's welcome page:

Return after 5 minutes and go back to Administration > ADMIN > Software Update to see if the software has been installed correctly. It is strongly recommended to immediately make another configuration backup.
