Simple apache2 redirect from one domain to another

What I want to do is the following:

My domain xy.example.com no longer exists. Thus I want to do a simple redirect to the new domain abc.example.com. It should be a redirect, that also works when someone types in the browser bar http://xy.example.com/team.php - than it shoul redirect to http://abc.example.com/team.php

I've already tried a few things, but it didn't really work. What do I have to put in the Apache 2 config?

You can use the RedirectPermanent directive to redirect the client to your new URL.

Just create a very simple VirtualHost for the old domain in which you redirect it to the new domain:

<VirtualHost *:80>
    ServerName xy.example.com
    RedirectPermanent / http://abc.example.com/
    # optionally add an AccessLog directive for
    # logging the requests and do some statistics
</VirtualHost>

Create or edit a .htaccess inside your DocumentRoot. Add

RewriteEngine On
RewriteRule ^(.*)$ http://abc.example.com/$1 [R=301,L]

Additionally I would change the ServerName directive to the new domain and leave a ServerAlias with the old domain.

ServerName abc.example.com
ServerAlias xy.example.com
