Upgrade Considerations

If you are upgrading from a previous release, perform a base installation into a new zFS. Many of the configuration file entries that are required for this release are similar to the entries required by previous releases. Therefore, retain the previous release HFS for your reference during the Post-Installation configuration phase.

If you are upgrading from a previous release of AT, and you do not intend to reinstall the mainframe Agents that you use, run the install_agents script. This script resides in the $AGENTWORKS_DIR/services/tools directory to register the Agents with this installation of AT. This script can be used to add or remove entries from the awservices.cfg file for any Agents or services that are currently supported on z/OS. Any of the mainframe Agents using AT must be started using the new CNSMLOAD and the new ENVFILE found in the CNSMOPTV data set.
