System Backup
You can back up a system database at any time. To ensure a successful
restoration of your database, be sure that the version number of the
backup file matches the version number of the system software.
For example, to restore the data on a system running release R6.0, use a
backup file from release R6.0, not from release R5.1 or lower. If you
restore a database that you saved on an older release, the operation will
succeed. However, if there is a change in the database schema between
the old and new releases, the restore will fail.
CAUTION: 3Com does not support the restoration of a database from an
older version of the system software.
3Com recommends this backup policy:

Back up your database before you upgrade the system software.
