We just got a call from a customer who's chassis died. ADI said it was an R6 that upgraded to an R9, so we used a newer chassis and swapped the card. Now it says there is no essential license available. There are 2 instances of additional essential VM ports, and 1 instance of an R9 upgrade. I have deleted and re-entered both of them with system reboots and I am still getting the same message. Not sure what to do - some of the older posts mentioned steps going from 6 to 9, but if this worked before is there a reason it wouldn't work in a new chassis? Thank you in advance.
