Migrating PVE server from grub (legacy BIOS mode) to UEFI

[astrakid]

hi,
i have a proxmox server installed years ago and upgraded from 4.x up to 7.3 currently. the server was installed in legacy bios mode.
firmware upgrades are not supported in this mode, so i would like to migrate to uefi. it is a single node installation (home server) with a couple of VMs on it. Additionally there are lots of scripts docker-containers on the host itself.

is there an inplace switch to UEFI possible?

kind regards,
andre

You didn't told us if you are using ZFS or not.

ah cool. first question after a quick look: i am running on ext4. would that work, too (clearly i wouldn't perform the zfs steps)?
