Importing Plesk 9.5.4 backup

Hi all.

I have Debian 6.0.3, webmin 1.570 and webmin-virtual-server 1.570.

I am trying to import the backup from Plesk 9.5.4. So I am trying to do
~ virtualmin migrate-domain --source /root/example.com_vhost_1112230101.tgz --type plesk9
and I am getting the following output:

Validating migration file …
… validation failed : Not a complete Plesk 8 backup file - missing XML file

Yes, it is not Plesk 8 backup. It is Plesk 9 backup. But what should I do with it?

Thanks in advance,
