Trying to move sites from one server to another

I am trying to move websites from one webserver to another. Both servers allow ftp and I have verified that I can log into ftp from the server I want to move to, to the server that I want to move from.

However, when I choose the option to transfer site with account username and password, enter the ip of the server, the domain I wish to move and the username and password, Cpanel comes back almost instantly with the following error:

Trying to fetch cpmove file via cPanel XML-API!
Fetching current backups from remote server....cPanel Login Failed
...............
Failed to fetch cpmove file via cPanel XML-API.
Trying to fetch cpmove file via ftp+cgi!
Attempting to login as gshutter to xx.xx.xx.xxx via ftp
FTP Login Failed

Can anyone tell me why this might be happening?

Thanks,

 

Thanks, using the other link worked perfectly. I guess the one I was choosing just doesn't work.

Thanks again,
