How to transfer Contacts from an old adroid devide

[isBlackNWhite]

I want to replace my mother's old Sony Ericsson Xperia Mini e10i, with a new smartphone.
But i am unable to transfer her Contacts... tried many ways like Sony sync, Gmail sync or apps.. but with no result.

Is there a manual way to extract them? or any tips?

Welcome to Android Central! I'm assuming all of her contacts are saved locally to the Phone account, and not to her Google account, correct? If she's logged into her Google account on her computer browser and goes to contacts.google.com, are any of her contacts there?

If they're all saved to the local Phone account, then open the Contacts app and tap Menu. Is there an option for Export?
