An Electronic Pre-installation Worksheet (EPW) file plays an important role in installing an Avaya Aura® solution template on System Platform. Creating an EPW file helps you set up and save those parameters required during the template installation ahead of time. When installing the template, you upload the EPW file and let the installation happen with minimal intervention. For example, obtain the required IP addresses before the installation and enter those IP addresses when you create the EPW file. Then when you upload the EPW file at the customer site, the IP addresses are automatically populated in the installation wizard.
To reinstall a template, reuse the original EPW with all the correct specifications.
To create the EPW file, use a stand-alone version of the installation wizard that you install on a Windows-based computer. The stand-alone installation wizard displays the same configuration pages that appear in the installation wizard. The configuration pages displayed by the stand-alone installation wizard depend on which template you install.
