The restoration procedure for the OfficeScan server requires that administrators uninstall the OfficeScan XG server, reinstall the older server version, manually stop Windows services, update the system registry, and replace OfficeScan server files in the OfficeScan installation directory.
Ensure that you roll back OfficeScan agents before restoring the OfficeScan server.
