Redirecting one domain to another properly

The only difference between abc.com and xyz.com is the url structure
Example domain abc.com/upload/ and the domain I am moving to is xyz.com

xyz has the forum installed in the root......

when a link to the old site on google is abc.com/upload/somefile.html
it is redirecting to xyz.com/upload/somefile.html.
I want it to point to xyz.com/somefile.html instead.

How do I do that? probably .htaccess in the abc.com right

Here is my .htaccess
Options +FollowSymLinks
RewriteEngine on
Redirect 301 / http://www.x y z.com/

Thanks

oops I probably put this in the wrong place
