Hi all,
We’re planning to upgrade our FTD 2100 series and FMC version to 6.6.4. Current version for both FTD and FMC were 6.6.1 and FTDs are in HA deployment.
I’m planning to upgrade our FTDs from FMC by installing the update patch.
But when we visit the FTD software download page, we found the file named “FXOS MIBs for Firepower 1000/2100 series” and we are not clear if we could directly upgrade our FTD from FMC without changing the current FXOS version.
Do we need to upgrade FXOS in FTD 2100 series if we want to upgrade FTD version? If it's needed, could please guide me how ?And also, I’d like to know whether I should upgrade the FMC or FTDs first?
As long as the FMC version is higher than FTD’s, it can still manage the FTDs right?
Thank you and kindly help!
