Redirect old domain to new one

[OldWolf]

I try 301, i thought i ll redirect all pages to new domain but all old pages gives 404 except homepage

here is my .htaccess

RewriteEngine on
RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^/?$ http://www.mynewdomain.com/ [R=301,L]

Is this code wrong or something is missing please.I just want all my ex pages redirect to new home page.
Thanks

You don't need the RewriteCond, since it doesn't do anything in your code anyway, and you do need to add a back-reference, so that the requested page is requested from the new domain:

RewriteEngine on
RewriteRule (.*) http://www.mynewdomain.com/$1 [R=301,L]

Ok i changed the code thanks but not understand what back-reference means, can you or someone give an example please .I renamed all pages ( was using a cms )and delete some of them so redirecting them to new homapage fine with me .

See back-reference as described under the RewriteRule directive in the Apache mod_rewrite documentation [httpd.apache.org]
