About iOS and iPadOS Upgrades

To check what operating system you have installed, go to Settings > General > About > Software Version. Wikipedia maintains a detailed comparison of iOS devices. The OIT recommends that all iOS and iPadOS devices be upgraded to the most recent version of iOS or iPadOS that your hardware allows for improved performance, security and functionality.

Before installing any iOS upgrade

• Be sure to check for and install updates to your individual applications
• Backup your device following the instructions below
• Also remember to have the device fully charged or plugged in while preforming the update
• Ensure you have any stored passwords available. You may be prompted to re-enter any previously saved passwords after an upgrade is applied
• Once an update has been applied, it may not be possible to downgrade to a previous version

The OIT provides basic support for current model iOS devices (generally 2 years old or newer) to enable users to connect to the ND wireless network, to access ND Google email and calendaring services, and any central IT service designed for mobile devices. For additional support, please contact your hardware vendor, cell phone carrier, or the provider of the software application.

Backup:

We strongly recommend running a backup of your device before installing any iOS or iPadOS upgrades to keep your data safe. The OIT recommends utilizing iCloud for iPhone and iPad backups.

• You can back up to iCloud from the device itself by going to Settings > AppleID/iCloud > iCloud > iCloud Backup > then turn iCloud Backup to ON. This will turn on automatic backups. To create a fresh backup, click Backup Now.
• While not recommended, backups to a Mac or Windows PC can be made.  See this guide for more information.  

Updating:

1. Plug your device into power and connect to the internet with Wi-Fi.
2. Go to Settings > General, then tap Software Update.
3. If you see two software update options available, choose the one that you want to install.
   
   
4. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now.
