Migrate proxmox 1.7 cluster to 1.8

[lozair]

Hi,
Reading the doc i found migration guide to upgrade from 1.7 to 1.8 proxmox version for one proxmox server.
I understand we must reboot the vm after the migration node.
My question is about cluster migration sequence.
Can i have my master node in 1.7 version and my slaves noces in 1.8.
The goal is to migrate smoothly to 1.8, we have 60 vms and we can't stop all these vms at the same time.
We want update to 1.8 on node and after another node etc.....

regards

Hello!

I did the same kind of migration last week. Worked without problems.
I could even live migrate VMs between 1.7 and 1.8 Nodes, so I had no downtime at all.

I updated the master node last. But I don't think it made any difference.

I'm assuming these live migrations were KVM VMs? At least based on what I've read, live migrations no longer work for OpenVZ unless you downgrade the kernel to 2.6.18.
