Cisco Cisco Firepower Management Center 4000

If you encounter any other issue with the update (for example, if a manual refresh of the page shows no 
progress for an extended period of time), do not restart the update. Instead, contact Support.

When the update completes, the appliance displays a success message and reboots. After the appliance 
finishes rebooting, refresh the page to log in and complete any required post-update steps.

When you apply a patch or feature update to a Cisco appliance, the update process creates an uninstaller 
that allows you to remove the update from that appliance, using its web interface.

When you uninstall an update, the resulting Cisco software version depends on the update path for your 
appliance. For example, consider a scenario where you updated an appliance directly from Version 5.0 
to Version 5.0.0.2. Uninstalling the Version 5.0.0.2 patch might result in an appliance running Version 
5.0.0.1, even though you never installed the Version 5.0.0.1 update. For information on the resulting 
Cisco software version when you uninstall an update, see the release notes.

Uninstalling from the web interface is not supported for major updates. If you updated your appliance 
to a new major version of the FireSIGHT System and you need to revert to an older version, contact 
Support.

Uninstall the update in the reverse order that you installed it. That is, first uninstall the update from 
managed devices, then from Defense Centers.

You must use the local web interface to uninstall updates; you cannot use the Defense Center to uninstall 
updates from managed devices. For information on uninstalling a patch from a device that does not have 
a local web interface (for example, virtual devices or Sourcefire Software for  X-Series), see the release 
notes.

Note that, although you can use this process to uninstall minor updates for Sourcefire Software for  
X-Series, you cannot use this process to uninstall the Sourcefire Software for  X-Series application from 
the X-Series platform. For more information, see the Sourcefire Software for  X-Series Installation 
Guide.

Clustered devices and Defense Centers in high availability pairs must run the same version of the 
FireSIGHT System. Although the uninstallation process triggers an automatic failover, appliances in 
mismatched pairs or clusters do not share configuration information, nor do they install or uninstall 
updates as part of their synchronization. If you need to uninstall an update from redundant appliances, 
plan to perform the uninstallations in immediate succession.

You cannot uninstall an update from devices in a clustered stack if uninstalling would revert these 
devices to a version in which clustered stacking is not supported.
