Apple has finally released the iOS9 and you’re probably excited to upgrade your OS right away. But before you do so, here are some things you should know first so you won’t have to delete any of your favorite apps, images, or videos.

Installing the iOS9 update will require 1.3GB — or even more space if you haven’t upgraded your Apple device for some time. During the iOS8 update last year, some users reported needing 5.7GB of free space to download the software.

This can be a big problem if your iPhone only has an internal storage of 8GB or 16GB. To go around this issue, the answer is simple: iTunes.

How to Install iOS9 With No Error Messages

Download the update through iTunes in your computer and transfer the software to your device. Thus, you won’t need to delete any data from your device to make space for the download. Do it through the computer, not over the air.

Steps:

1. Back up your iPhone, iPad, or iPod to your computer and iCloud.

2. Select “Check for Update” to install iOS9.

3. Don’t click “Restore iPhone” to avoid deleting any data.
