I am trying to upgrade to to version 6.x from 5.1r5a. I keep getting an error in the gui "An error occurred while executing the HiveManager software update command". This is an on-site version of HM. Has anyone experienced this before?
Are you upgrading using a local file or are you downloading the image during the upgrade? I recommend downloading the image file from the Aerohive Support site, storing it locally and upgrading using that image file.
