Before Installing Apple’s iOS 10, Review Our Critical To-Do List

By Mary Beth Hamilton | Tuesday, September 13th, 2016

The new Apple iOS version 10, that was released today, delivers some cool new features but before jumping in we recommend you review the following upgrade steps.

Here’s why.  As with any major update, there can be risks associated with early adoption until issues are uncovered and Apple has the time to debug and fix them. Eze Castle Integration has learned of some significant potential issues including risk of data loss due to incompatibilities with mobile device management (MDM) applications.

So here’s a critical to-do list before starting the iOS 10 upgrade.


  • Backup your device. Always take a backup before updating your device. 

1. The best way to do this is via WiFi at night when the device is also plugged into a power source (computer or electrical outlet). iCloud will back up your device on its own if configured correctly and provided you have enough storage. To ensure this is occurring, launch the Settings App -> iCloud -> Backup and see what it says next to “Last Backup:”. If it only states a time, then it means it backed up today and no further action is needed. If it says a date, you can back up the device by clicking “Back Up Now”. (Note: WiFi is required to back up this way). If this fails, you can back up to iTunes (see next bullet) or clients can call ECI’s Help Desk for assistance.

2. Alternatively, you can backup using iTunes. Plug the device into a computer, launch iTunes, right-click on your device and click “Back Up.” 

  • Manually backup passwords. Ensure you know your iCloud passwords, iTunes Store password, email passwords and any other critical passwords. Write them down and test them. Then safely and securely discard that information. As a best practice, there are secure password storage applications available through the App Store. 

  • Copy anything you can’t live without. Backup anything (i.e. photos) that you cannot live without. Do so in a way that you can verify the backup easily. One option is enabling iCloud Photo Library so you can access copies of your photos on all your other iOS devices. 


  • Update your MDM Apps. Simply launch the App Store on your iPhone (or iPad) and in the Updates tab, click Update on any AirWatch, XenMobile, MAAS360 or other MDM applications. Skipping this step could result in data loss if you don’t do it prior to updating your iOS. 

  • Before updating the iOS, prevent compatibility issues and update the rest of your apps. It is always best to make sure all your apps are up to date. This ensures greatest compatibility with new iOS versions. To do this, go to the App Store on your iPhone (or iPad) and in the Updates tab, click “Update All” in the upper right-hand corner. 

  • Update iTunes. If you ever plug your device into your computer, make sure iTunes is updated. When the new version of iOS 10 is available, Apple will also be releasing iTunes version 12.5 (the latest version is 12.4.3). To ensure you are running one of these two versions and have no compatibility issues, update to the latest available following one of these methods: 

Macs: Open iTunes. From the Menu Bar at the top of the computer screen, choose iTunes -> Check for Updates and follow the on-screen prompts.

Windows: Open iTunes. From the Menu Bar at the top of the iTunes window, choose Help -> Check for Updates and follow the on-screen prompts. 


  • Make sure you are on WiFi when you download the update as the update is large and will require WiFi. 

  • Plug into a power source when you are installing this update. It will take a long time for the update to install and requires the phone to have sufficient power. To manually start the update, go to Settings App -> General -> Software Update 

  • (Delaying until tonight.) If you get prompted to install the iOS update at a bad time, simply click “Later” like for past updates. You will be brought to a screen to agree to the Terms and Conditions and then type in your passcode. The update will then install overnight, if your device is plugged in and connected to WiFi.
