When you upgrade to VCS 7.3, you need not reconfigure application monitoring with VCS. All existing monitoring configurations are preserved.
You can upgrade VCS using one of the following methods:
Typical upgrade using product installer
Performing an online upgrade
Perform a script-based online upgrade of your installation to upgrade VCS without stopping your applications. The supported upgrade paths for the online upgrades are same as those documented under the script and web-based upgrades.
Automated upgrade using response files
You can upgrade VCS to InfoScale Availability 7.3 using the product installer or response files.
See the Veritas InfoScale Installation Guide.
