Before You Begin

Before you begin the update process for Version 6.0.1 Pre-Install, you should familiarize yourself with the behavior of the system during the update process, as well as with any compatibility issues or required pre- or post-update configuration changes.

A Firepower Management Center must be running at least Version 6.0.0 to install the Version 6.0.1 Pre-Install. If you are running an earlier version, you can obtain updates from the Support site.

The Version 6.0.1 Pre-Install only applies to Firepower Management Centers. Do not install the Version 6.0.1 Pre-Install on managed devices.

Caution: Cisco strongly recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.

For more information, see the following sections:

■Installing the Update

When to Perform the Update

Because the update process may affect traffic inspection, traffic flow, and link state, Cisco strongly recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.

Installation Method

Use the Firepower Management Center’s web interface to perform the update. Do not install the Version 6.0.1 Pre-install on managed devices.

Order of Installation

Update your Firepower Management Centers to Version 6.0.1 Pre-Install and then update the system to Version 6.0.1.

Caution: Do not reboot or shut down your appliances during the update until you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.

After the Installation

There are several additional post-update steps you should take to ensure that your deployment is performing properly. These include:

■verifying that the update succeeded

■making sure that all appliances in your deployment are communicating successfully

After installing the Version 6.0.1 Pre-Install on the Firepower Management Center and reapplying device configuration, update the system to Version 6.0.1.

The next sections include detailed instructions not only on performing the update, but also on completing any post-update steps. Make sure you complete all of the listed tasks.

Uninstalling the Pre-Install

If you need to uninstall the Version 6.0.1 Pre-Install, you must uninstall updates locally.

Use the following procedure to uninstall the Version 6.0.1 Pre-Install update from Firepower Management Centers and virtual Firepower Management Centers.

Uninstalling the Version 6.0.1 Pre-Install update results in a Firepower Management Center running the version the appliance updated from. For information on uninstalling a previous version, refer to the Firepower System Release Notes for that version.

To uninstall the update from a Firepower Management Center:

1. Log into the device as admin, via SSH or through the virtual console.

2. At the bash shell prompt, type sudo su -.

3. Type the admin password to continue the process with root privileges.

4. At the prompt, enter the following on a single line:

The uninstallation process begins.

Caution: If you encounter issues with the uninstallation, do not restart the uninstallation. Instead, contact Support.

5. After the uninstallation finishes, log into the managing Firepower Management Center and select Devices > Device Management. Confirm that the device where you uninstalled the update has the correct version listed.

6. Verify that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.
