Changing from Office Home/Student to Pro

Hi there,

I am currently running 2007 Office Home and Student version. I am looking
to go to Office 2007 Pro so that I will have Outlook and Publisher. Just
wondering, will I have to uninstall Office Home and Student before installing
Pro? I don't want to lose OneNote, I've enjoyed the options that it offers.
Is there a way that I can make the changes without losing OneNote?

Thanks for any advice on this subject
Take care
