Can i install proxmox 6.2 and keep old zfs Pool (without losing data) setup from previous proxmox 5.4-15

[Lonnon Jensen]

I have a current Server i am working on that will not upgrade to 6.2. Can i just install the proxmox 6.2 on a new drive and use (import) the existing proxmox 5.4-15 ZFSpool and not do a wipe or lose any of the data? i have googled this and clicked on just about every link without finding my answer.

Yes, that should be doable.

You have to backup /etc/pve/qemu-server/* /etc/pve/lxc/* and /etc/pve/storage.cfg - the best is to backup /etc/pve/*

Where do you have Proxmox installed on which disk? Is it in ZFS? Take care that the installer creates a "rpool" this name needs to be unique, so when you install ZFS with 6.2 it will also create an rpool.

Personally I would backup the rootfs of your PVE and upgrade it, the upgrade works nice.

Kind regards,
