Is there any way to upgrade from 32bit windows xp pro to 64bit xp pro without having to reformat and reinstall windows?

No, from the MS Windows XP x64 FAQ:

No, you can't upgrade. You can use the Technology Advancement Program until the end of July, 2005, to exchange your copy of Windows XP Professional for the x64 Edition of Windows XP Professional, but doing so replaces your existing license with the new license. The actual installation of Windows XP Professional x64 Edition is a fresh install, not an upgrade. All your programs will have to be reinstalled, and if you have data on the same drive as your operating system, it will be wiped out. Make a thorough backup of your important files before doing the installation.
