Where can I download iso image of proxmox 7.4-3?
Only found iso 7.4-1 - https://www.proxmox.com/en/downloads/proxmox-virtual-environment/iso

If you really want to, you could check the version of each installed Proxmox package on the 7.4-3 nodes and install that exact same version on the new node (after creating it with 7.4-1). But it's a lot of work and easy to make a mistake.There is no possibility to update, because there is hardware-bound software with license on virtual machines, which fails after proxmox update.
I don't know. Your current setup is End-Of-Life and unsupported and contains security issues and other known bugs.The cluster now has version 7.4-3, one node needs to be reinstalled. If two nodes will be 7.4-3 and one will be 7.4-1, is it not critical?
weird, it shouldn't, as VM has only virtual HW, software doesn't know anything about physical hardware or hypervisor updates, perhaps fails because another trigger.There is no possibility to update, because there is hardware-bound software with license on virtual machines, which fails after proxmox update.
no, clusters with different node minor versions should be no problem.Once again a question, cluster will not “fall apart” if two nodes will be 7.4-3 and one 7.4-1 ?
