Equipment to be used:
- FMC 2600 with version 6.6.4
- FTD 2130 with version 6.4.0.10
The objective is to upgrade the FTD to version 6.6.4 through the FMC.
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 deployment, including any managed devices:
Go to “Planning your Upgrade”.
Upgrade Procedure
1.- Deploy configurations
Deploy -> Deployment -> Select device -> 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.
2 .- Check disk space
System -> Monitoring -> Statistics
It is essential to check the disk space to make sure that the minimum required is met. On Firepower 2100 v6.6.4 requires 10.1 GB in /ngfw/var, 23 MB in /ngfw, and 1 GB in the FMC.
