How to Upgrade CA Performance Management Data Aggregator - Command Line

If you are upgrading from a previous release of Data Aggregator, upgrade your components.

Note: You can confirm what version of the product you have installed by looking at the .history file in the installation_directory/logs directory for each component.

Follow these steps:

The upgrade installer package contains the Migration Tool, which moves the existing vendor certifications to the appropriate directory.
