Access Site file using IP address.

I have a site .
This site was previously owned by another customer.
So after contract and negtiation and all, we changed the Domain and Server( Created new website)
Since current Url will point to newer site we created.
Is it possible to view the older site?
I have its IP address(old one) , Its credential , logins, apache , putty logins detals everything.
Since we need to have access to Database, MYSQL, We cant now login past admin screen. www.az-lily.com/admin because, we have already changed, DNS , name server and point it to New server.
As mentioned before, I have an access to its core files via putty.
Is it possible to view the website from IP address of the website?
If not , then How can I visit the site?
Just for information,The old server is still there, As I have an access to its FTP and all files are still there.
I have tried to access the page via ftp url [IPadress]/home/sv01/www/htmlremoving home and sv01 from here. But it gives me permission Denied.
