When you upgrade PowerExchange, depending on your requirements and environment, you can take one of the following approaches:
Existing install and data location. Install a new release of PowerExchange in the same location as an existing installation on the same machine. PowerExchange uses the existing data files from their current location.
You can use this option on platforms other than i5/OS, if you run only one version of the product.
New install location with existing data location. Install a new release of PowerExchange in a new location on the same machine as an existing installation. PowerExchange uses the existing data files from their current location.
You can use this option when you upgrade PowerExchange on Linux, UNIX, Windows, or z/OS, provided you are running only one version of the product. If you use this option on Windows, you must first remove the existing PowerExchange release.
New install and data location. Install a new release of PowerExchange in a new location on the same machine as the existing release. The new installation uses data files from the new location.
You can use this option on any operating system. You must use this option if you are running multiple versions of PowerExchange or if you are upgrading PowerExchange on IBM i (i5/OS). If you use this option on Windows, you must first remove the existing PowerExchange release.
For each scenario, the following topics describe the basic flow for installing software, copying data files, and editing configuration parameters and other variables.
