You can use the Veritas product installer to upgrade VCS as part of the Live Upgrade.

On a node in the cluster, run the installer on the alternate boot disk to upgrade VCS on all the nodes in the cluster. The program uninstalls the existing version of VCS on the alternate boot disk during the process.

At the end of the process the following occurs:

VCS 5.1 is installed on the alternate boot disk.

To perform Live Upgrade of VCS using the installer

Insert the product disc with VCS 5.1 or access your copy of the software on the network.
Run the installer script specifying the root path as the alternate boot disk:
```
# ./installer -upgrade -rootpath /altroot.5.10
```
Enter the names of the nodes that you want to upgrade to VCS 5.1.

The installer displays the list of packages to be installed or upgraded on the nodes.
Press Return to continue with the installation.
Verify that the version of the Veritas packages on the alternate boot disk is 5.1.
```
# pkginfo -R /altroot.5.10 -l VRTSpkgname
```
For example:
```
# pkginfo -R /altroot.5.10 -l VRTSvcs
```
Review the installation logs at /altroot.5.10/opt/VRTS/install/log.
