I have a 5508-X with firepower and need to upgrade the software. It is currently running a K8 version (9.8) so I need to go up to at lease 9.8.2.28 to prevent a vulnerability.
The problem is all (including my current version) is k8 versions and my teammate is insisting we need to use a k9 version. I can't find any.
Any one with knowledge or ideas?
Thanks,
Joe
