Before you update

Back up first Make a fresh backup to iCloud or your computer before you start. Apple: “Back up your device using iCloud or your computer.” Update your iPhone or iPad ↗
Know what a backup gives you Apple: “After you back up your iPhone or iPad, you have a copy of your information to use in case your device is ever replaced, lost, or damaged.” How to back up your iPhone or iPad with iCloud ↗
Plug in and use Wi-Fi Apple: “Plug your device into power and connect to the internet with Wi-Fi.” Update your iPhone or iPad ↗
Turn off VPN or proxy if the update won't download Apple: “Some software updates aren't available wirelessly. VPN or proxy connections might prevent your device from contacting the update servers.” Update your iPhone or iPad ↗

While it installs

If it asks for space, apps can be removed temporarily Apple: “If a message asks to temporarily remove apps because the software needs more space for the update, tap Continue to allow the system to remove apps. After installation is complete, those apps are automatically reinstalled.” Update your iPhone or iPad ↗

If you need to go back

Keep the backup you made before updating A backup made on the newer version may need that version to restore — the backup you make now matches the version you run today. Apple: “Your iCloud backup might need a newer version of iOS or iPadOS. If so, update your device before you restore.” Restore an iPhone, iPad, or iPod touch that needs a newer version of iOS or iPadOS ↗
