The best way I believe if is if you have the ability to use mod-rewrite? .htaccess files
A simple test would be to place a file which is named: .htaccess into the root of your server that looks something like this:
#==== .htaccess =========
Code:
redirect 301 /some-old/url.html http://www.anydomain.com/new-url.html
you can also use regular expressions to pattern match your urls so that you can do bulk re-directs in one go, but this may take a little working out:
