I did an in-place upgrade from PVE8 to PVE9 but after the update the kernel and zfs are still showing old versions even though they both seem to have updated:

Code: 
# pveversion
pve-manager/9.1.4/5ac30304265fbd8e (running kernel: 6.8.12-18-pve)

# uname -a
Linux ghar80 6.8.12-18-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.12-18 (2025-12-15T18:07Z) x86_64 GNU/Linux

# zfs version
zfs-2.3.4-pve1
zfs-kmod-2.2.9-pve1

 # [ -e  /sys/firmware/efi/efivars/ ] && echo "EFI" || echo "BIOS"
EFI

# cat /sys/module/zfs/version
2.2.9-pve1

I think it has something to do with the efi partition:

Bash: 
/boot/efi/loader/entries# ls
memtest.conf
proxmox-5.15.158-2-pve.conf
proxmox-6.8.12-18-pve.conf

# proxmox-boot-tool refresh
Running hook script 'proxmox-auto-removal'..
Running hook script 'zz-proxmox-boot'..
Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace..
No /etc/kernel/cmdline found - falling back to /proc/cmdline
/dev/disk/by-uuid/AED9-4562 contains no grub directory - skipping

Any ideas on how I can resolve this issue?

Well, what's in /boot?
And what does pveversion -v tell you, and apt policy proxmox-default-kernel proxmox-kernel-6.17 ?
I guess installing proxmox-kernel-6.17 will bring it to you, but maybe check further why it didn't update itself.
 
Unfortunately this could be one of the problems, as I originally started with PVE6 I have a lot of old version:

# ls /boot

I know that the new kernel did install as it is there but at boot it is only showing the PVE8 version and the PVE7..

Could it be that I need to force it by the changing the default in /etc/default/grub and replace "GRUB_DEFAULT=0" to the actual entry in /boot/grub/grub.cfg which seems to be 'Proxmox VE GNU/Linux, with Linux 6.17.4-2-pve'? Although I want to be careful since I don't want to crash the system and cause data loss
 
Please use code blocks. Try this and reboot
Bash: 
proxmox-boot-tool kernel unpin
proxmox-boot-tool refresh
 
Hmm, it's weird, can you run update-grub ? I'm guessing something went wrong when it tried to configure it..
Or maybe something like apt install --reinstall proxmox-kernel-6.17

Or proxmox-boot-tool commands from @Impact, though it's weird that update-grub didn't pick up the latest version.. but maybe it has, and indeed EFI conf doesn't know about it..

update-grub didn't help and neither did proxmox-boot-tool refresh but I tried that a while ago

None.

Automatically selected kernels:

Should this match the selection on bootup? see attached image from last bootup:

done
 
Tried the following so far:

Code: 
proxmox-boot-tool kernel unpin
proxmox-boot-tool refresh

and also:

Code: 
apt install --reinstall proxmox-kernel-6.17
reboot

made no difference.
