Starting from the AppDefense Appliance 2.3 release, you can now upgrade AppDefense Appliance with the Fail-Safe upgrade feature. If there is an upgrade failure, the Fail-Safe appliance upgrade reverts the appliance to the previous running version. Newly deployed 2.2.1 appliance version qualifies for the Fail-Safe upgrade.

  1. Make the appliance version compatible with the Fail-Safe upgrade feature. Follow the steps to Upgrade Appliance to Intermediate Version 2.2.1.
  2. Add an Additional Disk for Appliance VM. If you have directly installed 2.2.1 or later version (not upgraded), do NOT add an additional disk.
  3. Turn ON Auto Upgrade feature.
    1. Log in to the AppDefense Appliance.
    2. Go to the Appliance > Upgrade tab.
    3. Under the Appliance Upgrade Strategy section, click Edit, and then click Auto Upgrade.
    4. Click Save.
  4. The New Upgrade Available section becomes available with the Upgrade Now option.
  5. If your Appliance current version is less than or equal to 2.3.1.0, and registered vCenter Server version is less than or equal to 7.0, then first unregister AppDefense as described in Unregister and Reregister AppDefense Plug-In. Now proceed with Appliance upgrade.
  6. Click Upgrade Now. The Upgrade is in progress message appears. Appliance reboots automatically. AppDefense Appliance remains unreachable during this time. Ignore any errors from Appliance UI during this time. When the upgrade is in-progress, AppDefense Appliance restarts all the services.
  7. After the upgrade is complete, log in to AppDefense Appliance again. You can verify the Appliance version on the Appliance Dashboard page.
  8. After Appliance is upgraded, register AppDefense with vCenter Server again.
Note:

After upgrading to 2.3.2, if your get an ERROR: Unable to connect Appliance error message, then:

  • First unregister AppDefense as described in Unregister and Reregister AppDefense Plug-In.
  • Restart VMware vSphere Client service from the vCenter Server Appliance.
  • Now proceed with Appliance upgrade as described in this topic.
  • After Appliance is upgraded, register AppDefense with vCenter Server again.
  • Perform Config Sync for the host from AppDefense Manager.
