APNS Changes- Why You Must Upgrade to Windows Server 2016 or Above Now

feb 17, 2021 | 42Gears Team

APNS deprecation and how it affects SureMDM Customers

What are the APNs changes? 

APNs are push notifications platform by Apple that allows third-party application developers to send notifications to applications that are installed on Apple devices. So, these push notifications are key to sending MDM commands to a device. Initially, Apple released the first set of APNs in the year 2009, also known as binary APIs. Though these APNs were quite complex to the modern-day APIs, they were crucial for the speed of delivery. Six years later, in 2015, Apple released the second set of APIs, HTTP/2 API which is obviously more standard than the older APIs. Still, Apple continued to support and maintain the legacy binary APIs. But finally, in November 2019, Apple decided to stop the support for these legacy binary APIs.

Furthermore, in an announcement on October 9, 2020, Apple extended the deadline to update the (APNS) protocol from November 2020 to March 31, 2021. But what does it actually mean? It means this legacy binary protocol-based APNS from 2009 are deprecated and Apple will soon discontinue their support starting April 1, 2021. Instead, going forward, it will only support the modern, standard HTTP/2 APIs it released in 2015.

How Will This Affect SureMDM Customers?

Starting April 1, 2021, all customers using on-premise configurations of SureMDM must migrate to the  HTTP/2 based APNS mechanism in order to continue using SureMDM to manage Apple devices.

These Apple devices include iOS, iPadOS, macOS, and WatchOS devices.

42Gears has already issued the latest updates for SureMDM SaaS licenses to support modern APNS. This will help prevent any service disruption. 

All on-premise configuration customers must upgrade their systems to Windows Server 2016 or above. This upgrade holds a special significance because the changes require cipher suites that are present only in Windows Server 2016 and or above. 

Procedure to Upgrade-

Customers who run SureMDM On-Premise version 6.31 or below on Windows Server 2016 or above can follow-

Customers who run SureMDM On-Premise version 6.37 or above on Windows Server 2016 or above can follow-

Customers who have Windows Server 2012 R2 can also upgrade their systems to Windows Server 2016 and follow the instructions mentioned above.

Note – As a customer, you don’t need to upgrade the SureMDM On-Premise version. For instance, if you’re using SureMDM On-Premise v6.31, which is quite old, this latest patch will still be relevant for that version. Everything other than the APNS mechanism will continue to work the way it did in the original release of SureMDM On-Premise v.6.31.

Recently Apple advisory issued an update, which mandates customers to install a new root certificate on servers that send APNS notifications. For this, customers using SureMDM on-premise servers need to download the contents from the URL below and run a PowerShell script.

This new root certificate must be installed on the servers before March 29, 2021, in order to avoid push notifications delivery failure. Please note that customers using Windows Server 2012 need to upgrade to Windows Server 2016 before installing the new root certificate.
