Planing replacement of disk

[cglmicro]

Hi.

I'm running PBS on a server with 1 x NVME not in RAID (boot disk and where PBS is installed), and 4 x HDD in ZFS (contains all the backup).

The NVME is 50% wear out, and I'll need to replace it. The problem is that this server is in a datacenter, so I can't clone the OS to a new NVME.

Do you have a suggestion to a) export some config/settings, b) have the disk replaced, c) reinstall PBS, d) reconnect the ZPOOL, e) import settings, f) etc.
