Never import from a PST. There's no need and you lose data.

I want to export my outlook 2003 contact into windows contact.
How can i do to keep my data ?

Your contacts are in yoru PST. If you moved the PST to the Vista machine,
you should have access to everything it contains. Do you no longer wish to
use Outlook to contain your contacts?
