How to migrate an OpenVZ container from ploop to LXC?

Question

linux

There is an old server with OpenVZ.
There is a new server with LXC.

The container is spinning on the old one, the container FS is represented by 1 ploop file - root.hdd for 400GB.

How to transfer this VM to a new server and run it under LXC, with minimal hemorrhoids?
Is it necessary to deploy ploop on the FS of a new server? Or can you just run it like this?
In a debian 6 container, the old server is also on debian, will it have problems running on a new server with LXC on CentOS 7?
