The Windows Phone 7.5 operating system makes it easy to transfer contacts. Find the app "Transfer my data". On here you’ll find a simple Contacts Transfer app, tap it and make sure Bluetooth is switched on in your Nokia Lumia
This should (hopefully) be valid for your Lumia as well, even if the Windows version does not match.
Once it’s switched on you’ll find any devices in your area that are using Bluetooth and visible. Select your old Nokia phone and accept the pairing. One linked you’ll find that contacts are sent over automatically.
This should work with all Bluetooth-capable phones on the "other end". You might have to approve adding the contacts on the "receiving end", though – but you need not to involve any third-party cloud services for that.
