Why do you need to download (where did you downloaded from ?) , you can directly download and upgrade from appliance right ?

is it possible to download SMA version from ironport manifest and upload it.

[Ken Stieers]

Not upload it, but you can make it available on a web server locally and point the SMA at it to download it from there...

To be honest - I have not seen download and uploading.  done many upgrades we always content from  cisco download and do it upgrade ?

May try TAC they can suggest any other options
