We updated the former app "Switch to Windows Phone" and built this new version. It is preview version.
We are offering you two ways to move your data to Windows Phone:
(1) WiFi: if you’ve already set up your Windows phone. You’ll be able to move your contacts, text messages, photos, videos, and music over directly using virtual Wi-Fi and an app that you install on your new phone.
You do not need any network, real WiFi router or account. But you need to install a Windows Phone app on your Windows Phone. The name of the app is "Switch to Windows Phone". It's at https://www.windowsphone.com/en-us/store/app/switch-to-windows-phone/3286dd5d-3f98-435a-b80c-3fccba05a867
(2) OneDrive: if you haven’t set up your new phone yet. You’ll create a backup copy of your bookmarks, photos, videos, and apps, which can be downloaded automatically when you set up the new phone.
You need network connection and an Microsoft account.
