There’s something very important you need to know about the Apple Push Notification certificate. You need to renew it BEFORE it expires! If you don’t renew it before the expiration date you’ll need to re-register ALL of your Apple devices. Who wants to do that? Not me!
From my personal experience I can tell you that you can’t wait to renew the Apple Push Notification (APN) certificate a few hours before it expires. I’d suggest that at a minimum you renew it at least a few days before the end date.
Even though there are several blog posts and videos out there that will tell you how to install/create your APN certificate, I didn’t find many about how to renew the APN certificate.
It turns out that the renewal process is not that difficult. In fact it is almost identical to how you would install/create the APN certificate in the first place. I have lots of practice installing APN certificates in my labs configured with Intune and ConfigMgr 2012 and ConfigMgr Current Branch.
In order to help you out, I put together a short video showing the steps I took to renew my APN certificate in ConfigMgr. If you have never created an APN certificate, as I said before, the steps are ALMOST identical, so review the video and then do a quick internet search. You’ll find that you will have a better understanding of how to install/create an APN certificate for ConfigMgr too.
I hope you find this video helpful!
