Apple has published a migration guide for Android users wanting to shift to iPhones just one day before the release of the iOS 8 mobile operating system.

A detailed Apple support article provides tips on how to shift user data such as email, contacts, calendars, music, photos and videos, documents as well as e-books from Android to iPhone.
Apple also recommended the Copy My Data, AT&T Mobile Transfer and Photosync apps for shifting data stored on Android devices to iPhones.
The company also suggested using iTunes to move photos and videos, as well as music.
Customers who don't wish to move their music into iTunes are advised to use a streaming service like Pandora or Beats Music instead.
When it comes to migrating apps, Apple is only able to suggest searching the App Store to find equivalents to the apps already on the user's Android device.
There is no automated procedure to migrate to or finding equivalent apps for iPhones, whether they're paid or free.
The guide is aimed at mainly individual users wanting to shift personal data. Business users with managed devices are not specifically catered for but Apple touts its free Pages, Keynote and Numbers productivity apps as being able to read and edit documents.
Apple suggests uploading documents to the iCloud cloud storage after transferring them to a Mac or Windows PC using the Android File Transfer program. Once stored on iCloud, documents are accessible on both iPhones and computers.
