Before you upgrade on z/OS, complete the following tasks:
Verify that PowerExchange supports the versions and release levels of the operating system and data sources.
Verify that the license key is valid. If you have an existing InstParm file, it contains the license key. As part of the upgrade, you import the InstParm file. If you are adding new features, you might need a new license key.
Verify that the new PowerExchange release is compatible with your PowerCenter installation.
Verify that the z/OS Installation Assistant is installed on a 64-bit Windows system. The installation will fail if you attempt to run the z/OS Installation Assistant from a 32-bit system.
