ASDM version Upgrade Error

[itdesk]

Hello Friends,

I was try to upgrade ASDM version from 7.1(5)100 to 7.8.2. But upgrade process is aborted due to "Invalided http response” related issue. However i was finished ASA software upgrade without any issue under ASDM version from 7.1(5)100 environment. But i couldn’t complete ASDM upgrade. Please below error massage image.

I highly appreciate community members supports regarding this error resolment.

Thanks,

Hi,

Have you tried to copy the asdm file using the command line?

Hi John,

Thanks & appreciate your response.

I didn't. But I would like to say, problem has been sorted now.

I able to complete upgrade ASDM after downgrade ASA software.

Relevant issue is existing ASA software based and not a HTTP bases as per the massage says.

Thanks,

I have seen this error before when there was a mismatch in comaptible versions. 

What ASA software version are you running?
