Recovering a website once domain has been moved

Hi

I tried to use Snapshot to archive my website in the hope I could restore it to a new server – however when I came to recover it the folder was empty! I don't know why – I did have some issues with the configuration, but should have double checked that the backup was there.

Now, I have moved my domain to another server, and changed the IP.

On a positive note, I have not deleted the domain from the old server and can access the files for now via Plesk. All of the WP files are still there but of course I am unable to load the website as the domain has already moved. I am also unable to access them via regular ftp.

My question is – how can I recover my website from the old server and somehow restore it to the new server?

Regards, Paul
