I'm in the process of migrating an existing server to new hardware. The current server is using a dedicated boot drive and the backup data is stored in a ZFS raidz2 volume. Normally I would just move all the disks to the new server and job's done. However, in this case it also involves migrating from BIOS to EFI boot.

I can see two possible ways to do this:
  • Converting the boot drive to EFI-boot (seems like a lot of hassle and the PBS would be inaccessible in the meantime)
    • Convert the boot drive
    • Move all the disks to the new server
  • On the new server:
    • Do a clean PBS install
    • Shut down the PBS services
    • Copy the /etc/proxmox-backup directory from the old server
    • Move the ZFS drives to the new server
    • Import the zpool
    • Activate the PBS services.
Which option, if any, would You recommend?
