Website and FTP vanished

Hi, when I try to connect to any page of my website I get a 404 error.
When I try to see the files from the file manager in cPanel i get this message:

Are all my files gone?

When trying to connect with FileZilla i get a “421 Home directory not available - aborting”.
Obviously the missing home directory can’t be my fault.

This issue is caused by the system migration being currently in progress. More information about the migration can be found here:

Thank you for the support
