Upgrading a distributed InterScan Messaging Security Virtual Appliance (IMSVA) 8.5 environment to IMSVA 9.0

To upgrade from version 8.5 to 9.0:

1. Make sure all the IMSVA 8.5 servers are working properly and has IMSVA 8.5 Service Pack 1 applied.
2. Stop all of the IMSVA child servers' services using the commands:

   # cd /opt/trend/imss/script
   # ./imssstop.sh

3. Start all of IMSVA child servers’ database services using the command:

   # /opt/trend/imss/script/dbctl.sh start

4. Start upgrading the IMSVA parent server:
   1. Reboot the IMSVA parent server and boot from the IMSVA 9.0 installation CD.
   2. Upgrade the IMSVA parent server. Refer to the steps provided in the IMSVA Installation Guide topic: Upgrading a Single IMSVA. Perform only until Step 14 of the procedure.
       

      Do not execute the commands "/mnt/backup/dry_run.sh" and "/mnt/backup/confirm.sh" just yet.
   3. Verify the IMSVA parent server status.
      1. Double-check the /var/app_data/installlog file to confirm that it has been upgraded successfully using the commands:

         # more /var/app_data/installlog |grep -i suc

         You will see the following if the upgrade is successful:

         2014/10/13 15:57:03 CST [4050:-142723392] rpm/imsva-9.0-1.i386.rpm is installed successfully. [step.py:2182]
         2014/10/13 16:03:44 CST [4050:-142723392] Upgrade succeeded. [installer.py:268]

      2. Make sure that the IMSVA Database service is running, while other services are not running using the ocmmand:

         # ps -ef |grep imss
         imss     26303     1  0 18:22 ?        00:00:00 /opt/trend/imss/PostgreSQL/bin/postmaster -D /var/imss/pgdata -i

5. Start upgrading the IMSVA child servers.
   1. Reboot the IMSVA child server and boot from the IMSVA 9.0 installation CD.
   2. Upgrade the IMSVA child server. Follow the same steps as Step 3b.
   3. Verify the IMSVA child server is upgraded successfully.

      # more /var/app_data/installlog |grep -i suc

      You will see the following if the upgrade is successful:

      2014/10/13 16:34:17 CST [4038:-142895424] rpm/imsva-9.0-1.i386.rpm is installed successfully. [step.py:2182]
      2014/10/13 16:34:23 CST [4038:-142895424] Upgrade succeeded. [installer.py:268]

      For a multiple IMSVA child server environment, upgrade the child servers one by one with the same steps.

6. Execute following command on the IMSVA parent server:

   # cd /mnt/backup
   # ./dry_run.sh

7. Execute the same command on the IMSVA child servers.

   # cd /mnt/backup
   # ./dry_run.sh

8. Confirm that all of the IMSVA servers are working properly.
9. Execute the following command on the IMSVA parent server:
   # cd /mnt/backup
   # ./confirm.sh

   Select Yes when prompted.

10. Execute the same command on the IMSVA child servers.

    # cd /mnt/backup
    # ./confirm.sh

    Select Yes when prompted.

11. Confirm if all IMSVA servers works fine after the upgrade.
