If your old phone is a Windows Phone, the easiest way to transfer your contacts, calendar, and text messages to your new Lumia phone is your Microsoft account.
If you don't have a Microsoft account set up on your new Lumia phone yet, on the start screen, swipe down from the top of the screen, tap ALL SETTINGS > email+accounts > add an account, and create a Microsoft account following the instructions shown on the screen.
- To select what you want to back up to your Microsoft account,
on your previous Windows Phone device, tap Settings > backup.
Your contacts and calendar are backed up automatically to your Microsoft account.
- On your new Lumia phone, sign in to your Microsoft account. Your contacts, calendar, and text messages are automatically transferred to your new Lumia phone.
