Switch virtual host to a new server

Question

I'm trying to migrate virtual hosts entries to a new server but pages are still being served from the old server.

What I've done on the new server:

1. I have created entries for the domain name in sites-available and created symlinks in sites-enabled. Conf file looks like this

   <VirtualHost *:80>

   ServerName domain_name:80
   ServerAdmin email@admin.com
   DocumentRoot "/home/domain/Sites"
   DirectoryIndex index.html index.php
   

   </VirtualHost>

2. I have NameVirtualHosts *:80 activated in /etc/httpd/conf/httpd.conf

3. I edited /etc/hosts to include server_ip domain_name

On the old server, the only thing I've done is to remove the VirtualHost entry for the site I'm trying to move over.

But I still get content from the old server.

I'm not sure if there are other things I need to do on the old server to properly migrate the virtual hosts to the new server.
