Ironport v7.5.1-028 was avalible on one Ironport but not the other. And I may have been stupid and made the upgrade on the first, but then noticed not beeing able to upgrade to more than 7.1.5-017. Both were from 7.1.3-010. Avalible upgrades just dont list anything. (ERROR - No avalible upgrades)
Why is that?
So now my 2 nodes are on different releases.
