In this scenario we upgrade our nodes - one after the other - from IBM WAS ND V6.0.1 to V6.0.2 by installing the refresh pack using the Update Installer for WebSphere Software program. We refer to this program as Update Installer throughout this chapter.
The properties/version directory under the <install_root> contains data about WebSphere and its installed components, such as the build version and build date. Use the versionInfo command to display the fix and version level of the various components (but do not use versionInfo during a product up/downgrade!). Search for Product version information in the WebSphere InfoCenter to learn more about this.
