live migration from 1.9 to 2.1

[Ammler]

Hello

I have a current running proxmox 1.9 with openvz containers and a new proxmox 2.1 and wonder if I am able to run a live migration or at least a migation with very low downtime.

Is it possible to create a cluster with nodes of different proxmox versions?

What would you recommend to do?

first, see http://pve.proxmox.com/wiki/Upgrade_from_1.9_to_2.0

cluster is only possible with identical versions. vzmigrate can work, test it.
