Migration from Virtuozzo? Anyone?

Linux should be straight forward (but there is no special tool for this) as OpenVZ is the basis of virtuozzo for linux.
As Virtuozzo for Windows is a quite different from all other full virtualization systems like KVM this will be more like a reinstalling ... but never tried and depends what is running on win. If you find a tool for migration to vmware, then you can use this also for KVM.
 
i will post here, so not to open new thread...

has anyone maybe migrate windows from virtuozzo to proxmox? I need to migrate some servers and i would like to know if someone has some experiences whats the best practice?
