Migrated multiple accounts from one server to new, now only get default webpage for every account

I got a new server 2 days ago, and my existing server had 45 accounts on. I used the WHM trasnfer tool and transferred all the accounts to new servers. Then i logged into cloudflare and other domain registrars and changed the IP addresses to my new server and updated all the DNS records. For some reason, when ever i go to any of the websites being hosted on my new server, it takes me to the defaultwebpage.cgi file, i've cleared cache, tried on a VPN and online proxies, and all doing the same thing. Any ideas how i can fix this as I have a few clients complaining!
