Just went through it - there is no upgrade path to XP64 - must be a complete new install. I guess it's possible to do a dual boot if you wanted.
Prior to the actual install, be sure to verify that there are drivers available for your hardware and that your software add ons might have 64bit versions.
Also remember that any old 16bit programs will NOT run at all.
I found only one program that I have been using for years that wouldn't run under XP64 because it was a 16 bitter.
Other than that it was a smooth transition OS wise.
