Hi,
I upgraded to the pre patch upgrade in order to upgrade to 4.1.0, when selecting the upgrade 4.1.0 i get this message "You are uploading a large file, which is likely not a valid file. Please check it again." I downloaded it from adtran site so I don't know why I am getting this message.
Thanks in advanced,
wm
Make sure you are doing the patch (3.7.1-p05.patch) in Administration > Patch waiting a bit then restarting the admin web server
and uploading vWLAN-4-1-0-674765.img at the Administration > Platform Upgrade section.
