How to handle link parameters via htaccess?

Question

htaccess

Good afternoon.
I need to redirect from abc.com/param to test.bcd.com/?query=param via htaccess.
Wrote this:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^(www\.)?test\.bcd\.com$ [NC]
RewriteRule .* http://test.bcd.com/?query=%{REQUEST_URI} [R=301,L]

Am I thinking right? What else to fix?
