Upgrade FMCs in a High Availability

Upgrade FMCs in a High Availability

- in Security

Equipment to be used:

  • FMC 2600 with version

The objective is to upgrade the FMC in HA to version 6.6.4

Before you begin, I recommend that you read the official documentation on the Cisco site for further reference. This guide explains how to prepare for and complete a successful upgrade of a Firepower Management Center.

Go to “Planning your Upgrade”.

Upgrade Procedure

1.-  Deploy configurations

Deploy > Select devices/changes > deploy

Make sure there are no pending updates for the sensor you are looking to upgrade. Deploy any available changes before starting the upgrade process.
