IMSS now supports upgrading an entire distributed deployment, for example, in a network where IMSS is being used in a parent-child deployment.
Note
Note
IMSS 7.1 SP2 Patch 1 or above is required when upgrading or migrating.
If IP Profiler is deployed on an edge server while the scanner service runs on another downstream server, perform the following recommended tasks:
  1. Uninstall the IMSS 7.1 server where IP Profiler is installed.
  2. Upgrade the remaining IMSS 7.1 servers to 9.1.
  3. Enable the known host setting and IP Profiler.

Procedure

  1. Prepare for the upgrade.
    1. Back up IMSS settings.

    2. Use the following command to verify there are no messages in the Postfix queue:
      postqueue –p
    3. Make sure that all IMSS services are working properly on the management console.
      On the Summary screen, all the services under Managed Server Settings are active.
    4. Stop all services on child devices using the following command:
      # /opt/trend/imss/script/imssstop.sh stop
      Note
      Note
      In a distributed deployment, the parent device must be upgraded before child devices.
    5. Start the database service on child devices using the following command:
      # /opt/trend/imss/script/dbctl.sh start
  2. Upgrade the parent and child devices.
    1. Upgrade the parent device.
      For details, see Upgrading an IMSS Single Server Deployment.
    2. Use the following command to verify that the database is working properly on the parent device:
      # ps -ef |grep imss
      Information similar to the following appears:
      imss 5602 0.0 0.2 63412 3376 ? S Oct14 1:09 /opt/trend/imss/PostgreSQL/bin/postgres -D /var/imss/pgdata -i
    3. Upgrade all the child devices one at a time, a few at a time, or all at once.
      WARNING
      WARNING
      Do not restart IMSS services until all devices have been upgraded.
  3. Check information under Old Components That Need Upgrade and make sure all servers have been upgraded.

    Note
    To use Sender Filtering together with the Sendmail MTA, additional configurations must be done to ensure that Sendmail uses FoxLib and therefore gets the real IP address of the SMTP client contacting FoxProxy. For details, see Using Sender Filtering with Sendmail.
    Make sure you complete the configurations on each device.
