Migrate OpenVZ containers from an existing Proxmox install to a clean install

[azop]

I'm moving between datacenters, and I need to copy my containers to a (clean) install of Proxmox. Once I move everything from the existing server to the new server, I'm going to take that server offline.

How should I do this? I thought vzmigrate would do what I wanted, but after running it the new container doesn't pop up in the Proxmox web interface.

I've searched the forums and I haven't found anything useful. I thought about online cluster migration, but I'm concerned that I might break something, plus I will only have one server running after I remove the original server after I move the containers.

Hi,
backup and restore is the normal way (ok, with downtime).

What is the procedure? I try with one ct, v2 to v2 and also v1.9 to v2 ? But doens't match anywhere?!

I have had a range of proxmox 1 series. 1.7 - 1.9.

All you do is install the SSH keys on the node so you can logon with no password.

Then...


1 by 1.

vzmigrate --keep-dst --remove-area no -v <proxmox2 ip> <ct id>

Do not try do an online migration. This will not work.

Sorry to necro this year old thread.

I've got an old 1.x cluster running, and a new 2.x cluster also running (Two separate clusters) . Can I just vzmigrate the openvz containers from the old cluster to the new one, just specifying the new server's IP from the old one? If that's all I have to do, this migration is going to be easy.

Also, I do have a couple KVMs, would I migrate them the same way, or do I need to figure something else out?

Thanks.
