Upgrade fr 32 to 64 bit Win7 drive compatibility

Cannot locate something specifically addressing this topic - perhaps because it is not a problem.  Am considering moving from 32 bit Win 7 to 64 bit.  Will my NTFS WD “E” drive (documents, games etc.) be automatically read as-is after I make the switch or will I have to reformat, or…?  thanks

will do with no problem… no need to reformat
