We have an urgent situation to try and get our Cisco Firewalls/Firepower devices up to the latest 6.2.2.x version.
We currently have the following environment with devices running in HA (Active-Standby) so 2 devices of each below.
Firepower Management Center = 188.8.131.52
2 x FTD 4110 > Firepower = 184.108.40.206 , FXOS = 2.1(1.72)(1)
2 x ASA5516X-SFR > ASA = 9.5.3, Firepower = 220.127.116.11
2 x ASA5516X with FTD > Firepower = 18.104.22.168
What are the upgrade procedures (and version path) to get all these devices up to version 6.2.2.x
Cisco's Compatibility Matrix is not the most clear.
