To upgrade the PCNS Virtual Appliance, you do not need to deploy a new copy of the Appliance and run the Setup Wizard.
You can now upgrade the version of PCNS running on the Virtual Appliance using the ESXi installation files: This method will retain your existing configuration settings.
Download the latest version of the PCNS for VMware ESXi installation file to your local PC. For example, the ESXi installation file for v4.1 is available from the link below:
Login to the Virtual Appliance console as the root user using PuTTY or other SSH Client.

sudo mkdir /opt/temp
Copy the previously downloaded installation file from your local PC to the temporary directory using WinSCP or other FTP/SCP program.
In the console, change to the temporary directory and uncompress the installation file
gunzip pcns410ESXi.tar.gz tar -xvf pcns410ESXi.tar

Run the installation script and follow the instructions
