Uninstalling the Update

Uninstalling the Update from a Defense Center

Use the following procedure to uninstall the Version 5.2.0.5 update from Defense 

Centers and virtual Defense Centers. Note that the uninstallation process reboots 

the Defense Center.
Uninstalling the Version 5.2.0.5 update results in a Defense Center running 

Version 5.2.0.5. For information on uninstalling a previous version, refer to the 

release notes for that version.

To uninstall the update:

1. Read and understand 

 on page 15.

2. Make sure that the appliances in your deployment are successfully 

communicating and that there are no issues reported by the health monitor.

3. View the task queue (System > Monitoring > Task Status) to make sure that 

there are no tasks in progress.
Tasks that are running when the uninstallation begins are stopped, become 

failed tasks, and cannot be resumed; you must manually delete them from 

the task queue after the uninstallation completes. The task queue 

automatically refreshes every 10 seconds. You must wait until any 

long-running tasks are complete before you begin the uninstallation.

4. Select System > Updates.

The Product Updates tab appears.

5. Click the install icon next to the uninstaller that matches the update you want 

to remove.
The Install Update page appears. 

6. Select the Defense Center and click Install, then confirm that you want to 

uninstall the update and reboot the device.
The uninstallation process begins. You can monitor the uninstallation 

progress in the task queue (System > Monitoring > Task Status).

Do not use the web interface to perform any other tasks until 

the uninstallation has completed and the Defense Center reboots. Before the 

uninstallation completes, the web interface may become unavailable and the 

Defense Center may log you out. This is expected behavior; log in again to 

view the task queue. If the uninstallation is still running, do not use the web 

interface until the uninstallation has completed. If you encounter issues with 

the uninstallation (for example, if the task queue indicates that the update has 

failed or if a manual refresh of the task queue shows no progress for several 

minutes), do not restart the uninstallation. Instead, contact Support.
