problems restoring old backup pve1 => pve5

I have to restore a very old backup (vzdumped from a proxmox 1.9, storage local)
to a new server (bleeding edge : pve5.3, storage local-zfs)

I tried :
# qmrestore --storage local-zfs /media/usb/vzdump-qemu-102-2019_01_03-13_31_37.tgz 102

but it gives :
VM is locked (create)

I also tried :
# zcat /media/usb/vzdump-qemu-102-2019_01_03-13_31_37.tgz | qmrestore - 102 --storage local-zfs

It throws:
restore vma archive: vma extract -v -r /var/tmp/vzdumptmp6793.fifo - /var/tmp/vzdumptmp6793

command 'set -o pipefail && vma extract -v -r /var/tmp/vzdumptmp6793.fifo - /var/tmp/vzdumptmp6793' failed: got timeout

dump formats not compatible ?
is there any procedure to achieve such a messy restoration ?
any file conversion i can try ?

While not very strong (the raid1 pile died during the second vm backup)
The old (pve1) server is still available

Kind Regards

Argh, damn it :D

From this site:
you have to use:
qmrestore /media/usb/vzdump-qemu-102-2019_01_03-13_31_37.tgz 102 --storage local-zfs
but i dont know if this really change anything at this, but maybe.

Do you have the Config File of the VM and can paste it here? Is the ID 102 already in use?
You can try "qm unlock 102".

Before you retry, remove all leftovers from the fault try.
This is a old, unsupported tar backup. You can try to manually extract the files using the standard tar command.
