i tunes library to new

Hmm not sure if you can sync a new iPhone to any version of iTunes that runs on a windows XP computer.

You may try to move the library to a newer computer first:

Move your iTunes library to another computer - Apple Support

And then sync it

This article explains how:

Use iTunes to sync your iPhone, iPad, or iPod with your computer - Apple Support

Good luck!

I agree with Androish.

Which version of iTunes are you using?
