Upgrading from an earlier version
When you upgrade the Directory Synchronization Client from an earlier version, the configuration and settings files are also upgraded to the new version. Backup copies of the original XML settings files are made in the same location as the original XML files. The backup files are named settings.xml.old and can safely be deleted if you are not planning to revert to the previous version of the application.
The application settings are upgraded when the application is first started. The configuration settings are upgraded when a configuration is saved.
