XP Pro Machine to Windows 2000 Domain

I have a few employees in my agency who have laptops with xp pro on them and they have already established a profile and they have emails & files saved under their profile. If I add them to the domain within the network, it creates a new profile on the XP Pro machine. I then have to copy emails, addresses, favorites, etc. to the new profile. Is there a way I can get around this?
