What if my upgrade to iCloud Drive pauses or doesn't respond?

Check your Internet connection. In your iOS device’s status bar, look for an Edge, 3G, 4G, LTE, or Wi-Fi icon. On your computer, look in your local network utility for an active wired or wireless network connection. Then open a website from your browser to make sure you're connected. You can use these steps to check your Internet connection on your Mac or iOS device.

 

If you lose your Internet connection, the upgrade will pause for a short time, then try again. If your upgrade still doesn't respond, contact Apple Support.

Note the time to upload data can vary greaty depending on your amount and Internet connection.

Regards,

Nubz
