In Redirect all pages of one TLD to another there's a clear example of how to Redirect from the root of one TLD to the root of another TLD. But I want add a Rewrite Condition & Rule to my .htaccess file that will do the following redirects...
www.example.com/one --> www.example.co.uk
www.example.com/one/two --> www.example.co.uk/two
www.example.com/one/two/three --> www.example.co.uk/two/three
So basically it will redirect the URL to one where the TLD is changed and the first directory in the path (/one) is removed.
