In this scenario, you install the PowerExchange software into a different location from the previous installation, and you create a new location for your PowerExchange data files.
Where possible, you then copy the PowerExchange data files from the previous release that you intend to use with the new release to the new data location. You also update configuration parameters and other variables to point to the new location of the data.
This approach does not work for all PowerExchange data. For example, you cannot use new data set names for the PowerExchange Logger for z/OS active and archive logs and then copy the existing data. For the PowerExchange Logger for z/OS, you must either keep the existing names or lose all existing captured data.
Use the following process:
Follow the instructions in this guide for performing a full installation, rather than an upgrade installation. Specify an installation directory that is different from the location of the old installation.
If you are installing a new PowerExchange release on z/OS, use the full installation option in the z/OS Installation Assistant. On z/OS, this option does not allow you to keep previously captured change data. If you need to keep previously captured change data on z/OS, you must follow the steps in New Install Location with Existing Data Location Scenario.
Copy the PowerExchange data files and libraries from the previous installation to the new environment. However, you cannot use this approach for CDC on z/OS.
Set configuration parameters, environment variables, automation and scripts, and DD statements to point to the new data environment.
