Equipment to be used:
- FMC 2600 with version 6.4.0.10
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.

3 .- Check disk space
System -> Monitoring -> Statistics
It is essential to check the disk space to ensure that the minimum required is met. The FMC v6.6.4 requires 15.1 GB in /Volume and 23 MB in /.
