About upgrading software components

You can install new releases of the VCS software components on your existing hardware. Component
upgrades can be performed in one of two ways:
Using the web interface
n
Using secure copy (SCP/PSCP).
n
This guide describes how both of these methods are used to perform upgrades. You can also upgrade the
System platform component using Cisco TMS (see the Cisco TMS documentation for more information).
We recommended that you upgrade VCS components while the system is inactive.

If you are upgrading a cluster, you must follow the directions in
n
Deployment Guide
If you are currently running non-clustered VCS X5.1, X5.1.1 or X5.2, you must first upgrade to X6.1, then
n
upgrade from X6.1 to X8.n.
If you are currently running non-clustered VCS X5.0 or earlier, you must first upgrade to X5.2, then upgrade
n
from X5.2 to X6.1, and then upgrade from X6.1 to X8.n.
VCS software components
All existing installed components are listed on the
current version and associated release key where appropriate.
The main component is the System platform, and when upgraded this will typically include automatic
upgrades of some or all of the other components. However, you can independently upgrade the other
components if required to do so. The upgrade process ensures that compatibility is maintained across all
components.
Upgrade prerequisites
The upgrade requires you to have:
a valid Release key, if you are upgrading to the next major release of the System platform, for example
n
from X7.2 to X8.1; it is not required for dot releases, for example X8.1 to X8.2
a software image file for the component you want to upgrade, and it is stored in a network location that is
n
locally accessible from your client computer; use the standard .tar.gz software image file when upgrading a
virtual machine (the .ova file is only required for the initial install of the VCS software on VMware)
release notes for the software version you are upgrading to — additional manual steps may be required
n
Contact your Cisco representative for more information on how to obtain these.
Backing up before upgrading
You should backup your system configuration before upgrading. Click
and restore page.
Upgrading and option keys
All existing option keys are retained through the upgrade from one version of the System platform to the
next, including upgrades to the next major release. However, you are recommended to take note of your
existing option keys before performing the upgrade.
Cisco VCS Administrator Guide (X8.1.1)
- this is the recommended process.
