You don't copy the entire profile. Only copy desktop, downloads, documents, music, videos, pictures, favorites, and any .pst files in C:\users\<username>\AppData\Local\Microsoft\Outlook
You don't want the rest because there are pointers in there that reference locations that only exist in 64-bit land, and you'll never fix it all by hand.
Exactly when transferring profiles weather it be roaming or not. Thats the only way I have found that works. Very tedious.
