I recently took a full-time position with a company for whom I used to consult on their Jamf instance. It had been a little over a year since I was on the system and in the meantime there had been a few other people with their hands inside it though it was mostly perceived as stable and left alone.

But I recently discovered that in the intervening year, the APNS cert had expired. A new certificate was created (with a different AppleID) and the handful of iOS devices were re-enrolled. Since the Macs were still checking in, it was assumed that nothing needed to be done.

I managed to find the original AppleID and found the cert under that login had been renewed at the same time. But it was the cert with the new login was uploaded to Jamf instead.

I have both certs downloaded and I created an extension attribute to determine which computers have which cert topic. Of the computers that have reported in, it's almost 50/50!

So I have a large number of computers that are still checking in but not taking MDM commands. 

Is there ANY way that I can fix this remotely?
