ZFS upgrade Proxmox 7

[scontin]

Hello,

I'm a bit confused.
I have an old Proxmox 5.3 upgraded to 6.4, with BIOS grub and ZFS on root

pveversion
pve-manager/6.4-13/9f411e79 (running kernel: 5.4.106-1-pve)

findmnt /
TARGET SOURCE FSTYPE OPTIONS
/ rpool/ROOT/pve-1 zfs rw,relatime,xattr,noacl


lsblk -o +FSTYPE

If I upgrade to newer Proxmox 7, can I brake boot?
I have no 512 M partition where get proxmox-boot-tool.


Best regards
