Can’t upgrade to iCloud Drive in new phone

Before you begin

1. Update your iPhone, iPad, or iPod touch to the latest iOS or iPadOS, and your Mac to the latest macOS.
2. Set up iCloud on all of your devices.
3. Make sure that you’re signed in to iCloud with the same Apple ID on all of your devices.
4. If you have a Windows PC, update to Windows 7 or later and download iCloud for Windows.

If you have a device that can't update to the latest iOS or macOS, see the minimum system requirementsto use iCloud Drive.

Hope the above helps.
