Hello,

I have a very old PBS (2.4-7) and would like to replace it with a new one. How can I do this without having to reconfigure the PVE cluster?

Can I copy the datastore from the old one to the new one? Copy the SSH keys and the contents of /etc/proxmox-backup?
 
Hi NoLine,

You'll be copying over the data, but reusing the configuration? Only connection data, or also storage layout?

I went through a similar exercise recently, but ended up with only the hostname preserved. Less than ideal, but re-adding certificates to PBS and adding PBS to the clusters was not too much of a hassle.

Is a large number of clusters and datastores involved?
 
  1. Upgrade your legacy server to latest PBS following the docs.
  2. Check if you are booting into legacy bios or UEFI. If legacy bios, migrate to UEFI: https://forum.proxmox.com/threads/h...to-uefi-boot-systemd-boot.120531/#post-523763
  3. Move your SSDs/HDDs to the new hardware.
  4. Configure your new hardware's to boot from your existing PBS.
  5. Configure your network interface. Get your new network adapter name from `ip link show`, modify /etc/network/interfaces and reboot.
