It has gotten to the point where the most difficult part of upgrading the ADC is clearing space on the drive. I knew you could delete temp files, traces, old installers, etc…but this trick is to delete the .tar.gz after it is extracted.
This will free up a good amount of space and hopefully allow you to do your upgrade.
Delete the .tar.gz from /var/nsinstall after it extracting it through the cli. Then run the install. :)
