    Hi,

    I have two clusters:
    • old_cluster Promox 4.4 with 4 nodes
    • new_cluster Proxmox 5.2 with 1 node
    I want to migrate all nodes in new_cluster and I know how to do that:
    • backup all VMs of a node
    • remove node from old_cluster
    • upgrade node to Proxmox 5.2
    • add node to new_cluster
    I just have a question mark about the step after I have removed the node.

    I want to keep the same hostname and ip of each node, but as described in the documentation to remove a node from a cluster, there is a warning:
    ATTENTION: at this point you must power off the node to be removed and make sure that it will not power on again (in the network) as it is.

    How can I proceed without completly reinstalling the node ?

    Regards,

    Christian.

    Well, just don't reinstall it. Turn off the old node, change another node's IP address after the VMs have been moved and maybe do an ARP flush.

    Thanks for your replies.

    I will follow Wolfgang's solution and upgrade the old cluster.

    Best regards,
    Christian
