How to move existing kvm virtual machines (PVE 3.3) to a new (PVE 5.0) Proxmox installation?

[adfs1]

Hello!

I have a two node cluster (PVE 3.3)
My shared storage is LVM on top of an iscsi storage.
I'm using only KVM quests.
The quests virtual disks is on this shared LVM-iscsi storage.
All virtual disks is an lvm logical volume.

I want to reinstall the hypervisors (PVE 5) from scratch, but keep this logical volumes untouched.

Can I use this virtual disks (on the shared lvm-iscsi), and attach this image to the new hypervisor?

This should in general work, but best you have a backup for just in case. You need to copy your vmid.conf files from the remaining node to the new one. Also while you can do a two node cluster, for quorum you need at least three nodes (majority vote).
