Appliance Replacement Considerations
Replacing an appliance should be done in such a way that no data is lost during the transition.
Following these recommendations will help prevent data loss:
• Scheduled jobs should be included when backing up an appliance before synchronization. This will
save you valuable time when restoring the backup on a new appliance. Unless you have backed up
your scheduled jobs, you will have to recreate them on the new appliance.
• Hold onto the old appliance until you have retrieved all important data from the appliance's hard
drive. Forensic data and other important data need to be backed up from the old appliance
especially if you need the data for auditing purposes.
• You should install the new appliance on a lab network not connected to the LAN/WAN. Do not place
the appliance on the WAN until you have restored the backed up configuration. The Sensors will
connect to the appliance and your network tree will not be set up. Once connected to a lab network,
you can either restore the primary's configuration file, or restore the configuration from a secondary
appliance to the primary appliance. If the configuration is restored from the secondary appliance,
you should then change the IP address of the new appliance to the one for the old appliance, reboot,
and install the new appliance on the network.
• Once the new appliance is on the network, back up forensic data from the secondary appliance as
required.
• ADSP restores the configuration long before the screen indicates that the process is complete.
Executing a ping to the appliance will let you know exactly when the system is up. Once you receive
a response, you can then log back in.
Account Management
Account Management allows you to:
• Create and modify user accounts and group accounts (Accounts Access feature)
• Authenticate users on the local appliance (Local Authentication feature)
• Change the password of the current user (Password Reset feature)
• Authenticate users by using the password stored on a RADIUS or LDAP server (Remote
Authentication feature)
• Specify the user preferences that are used to set the ADSP auto refresh rate and to specify a proxy
to access the server (User Preferences).
