Before you start to perform the upgrade, use the attached upgrade spreadsheet to gather the installation parameter values that are required by the installers. If you have a record of the values that you entered during installation, you can gather the values from those records.
During upgrade, many of the fields in the installer panels are either skipped or pre-populated. For example, you are not prompted for database information, because the database information is already part of your system configuration. The attached spreadsheet contains only the fields that are prompted during an upgrade.
