Import Or Export OE Mail To Outlook?

I've got an old PC running WinXP and I have always used OE 6 on it but I DO have Outlook 2007 loaded onto the same machine.I want to migrate all my email and address book to my new machine running Win 7 Ultimate x64.I know I can either IMPORT the emails with Outlook 2007 from OE.OR. I can EXPORT the emails using using OE 6.... correct ?I read somewhere that if I used the Import function I woul dlose the date/time stamp on my old emails. Is that true ?To Import the OE emails thru Outlook and then back the pst up and move it to my new machine.... or us e the Export function on EO to try to export the email to Outlook ?And once I get the email and addresses into Outlook 2007 on my old machine, should I use a Memory stick to move them to the new machine or try to use the Windows Easy Transfer and an easy transfer cable (which I already have)?
