I using c7 220.127.116.11.
In transfering from C5 to C7 I used the suggestion to rename new C7 DNI's to x?? to flag devices needing to be transfered to C7. This has been working but with new release the devices are not deletable (error 500) and the DNI field is not editable to change to a valid hex number.
Just a caution if anyone is in the process. Any ideas would be appreciated. I have submitted a support ticket.
