The Save Response File option on the Upgrade Summary screen creates a file that uses the information you have already provided in the Upgrade Assistant screens. The response file enables you to use the saved information instead of manually entering data through the Upgrade Assistant wizard screens.
Once you select the Save Response File option, you will be prompted for a name and location where you want to create this response file. After it is created, you can use it exactly as-is to replicate the upgrade options on other systems, or modify it as needed.
