If you want to continue using the property information (such as ubroker.properties, conmgr.properties, or proxygen.preferences) that OpenEdge automatically saved prior to the current installation, copy the saved property files from %TEMP% to OpenEdge-install-dir\properties. For information about the automatic save of the property information before the installation process occurs, see OpenEdge automatic save of properties files. For information on merging property files, see Mergeproputility overview.

You will also need to perform any other postinstallation tasks as discussed in PostInstallation Considerations and Performing an OpenEdge Installation in Windows.
