Step 4. Run the z/OS Installation Assistant to Upgrade

To perform a PowerExchange upgrade, you must run the z/OS Installation Assistant wizard on the Windows system.

Also, copy the existing InstParm file from the last full installation of the current PowerExchange version to your working directory on Windows. You can either manually copy the file before you start the z/OS Installation Assistant or you can import the file from a subsequent z/OS Installation Assistant page. As you progress through the z/OS Installation Assistant pages, you can save your entries to the InstParm file by clicking

Save

on any page.

Retain the InstParm file on Windows so that you can use it to upgrade or apply hotfixes to PowerExchange later.

On some pages, you can click

Advanced Parms

to define advanced parameters or click

Restore Defaults

to restore the default values. However, if you define advanced parameters, you cannot restore the default values later by using the

Restore Defaults

button.
