Uninstalling the Update

Planning the Uninstallation
Before you uninstall the update, you must thoroughly read and understand the
following sections.
Uninstallation Method
You must uninstall updates locally. You cannot use a Defense Center to uninstall
the update from a managed device.
For all physical appliances and virtual Defense Centers, uninstall the update using
For all physical appliances and virtual Defense Centers, uninstall the update using
the local web interface. Because virtual managed devices do not have a web
interface, you must use the shell to uninstall the update.
Order of Uninstallation
Uninstall the update in the reverse order that you installed it. That is, first uninstall
the update from managed devices, then from Defense Centers.
Uninstalling the Update from Clustered or Paired Appliances
Clustered devices and Defense Centers in high availability pairs must run the
same version of the Sourcefire 3D 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.
To ensure continuity of operations, uninstall the update from clustered devices
To ensure continuity of operations, uninstall the update from clustered devices
and paired Defense Centers one at a time. First, uninstall the update from the
secondary appliance. Wait until the uninstallation process completes, then
immediately uninstall the update from the primary appliance.
WARNING!
If the uninstallation process on a clustered device or paired Defense
Center fails, do not restart the uninstall or change configurations on its peer.
Instead, contact Support.
Uninstalling the Update from Stacked Devices
All devices in a stack must run the same version of the Sourcefire 3D System.
Uninstalling the update from any of the stacked devices causes the devices in
that stack to enter a limited, mixed-version state.
