Hello,
@sialeh. Could you please confirm the full path to the document root of the website in question, e.g. /var/www/vhosts/example.com/httpdocs? Also, can you double-check if there are any mod_rewrite rules? If there's an .htaccess file, please try temporarily renaming it (e.g. .htaccess.bk) and attempt to start the migration again.
