If you have one or more individual Scanners, you do not have to update all of
your Scanners at the same time. For example, you can update some Scanners
to version 7.5 and leave some with the older version so that some Scanners
continue to protect your site while you migrate others. However, a Symantec
Mail Security 7.5 Control Center cannot make configuration changes to a
pre-version 7.5 Scanner. A pre-version 7.5 Control Center cannot make
configuration changes to a version 7.5 Scanner. But in both of these cases, a
Scanner that was previously working will continue to work as before. However,
no log or report data will be forwarded to the Control Center.
Backing up existing Control Center data
It's recommended to back up your existing data to a separate computer in case a
problem occurs during migration. Follow this procedure on your existing Control
Center to back up your existing data before migration. You can also back up your
data using the db-backup on the command line interface.
To back up your existing data
1
It's a good idea to reduce the amount of data to be backed up. For example,
these measures can reduce the amount of data backed up:
■
Reduce the maximum log size or reduce the length of time that log data
is stored.
■
Clear all report data or reduce the length of time that report data is stored.
■
Delete old messages in Spam Quarantine or reduce the number of days to
store Spam Quarantine messages.
If you reduce the length of time that log, report, or Spam Quarantine data is
stored or reduce the maximum log size, you must wait for the applicable
Expunger process to run to delete the extra data.
2
In the Control Center, click Administration > Backup.
3
Back up your existing data to a remote location using FTP.
For detailed instructions, refer to the online help or Symantec Mail Security
Implementation or Administration Guide for your product version.
4
If your backup completes successfully, proceed with migration.
If your backup fails, attempt to further reduce the amount of data backed up
as described in step 1.
