What does

gpart list

show on your new disk ?

When I do a bare metal restore, I do something like this

echo ""
echo "# Create zfs boot (512k) and a 220 gig root partition"
gpart create -s gpt $DESTDEVICE
gpart add -a 4k -s 40M -t efi $DESTDEVICE
gpart add -a 4k  -s 8G -t freebsd-swap -l swap1 $DESTDEVICE
gpart add -a 4k  -t freebsd-zfs -l $DISKNAME $DESTDEVICE
newfs_msdos -F 32 -c 1 /dev/${DESTDEVICE}p1
mkdir -p /mnttmp
mount -t msdosfs /dev/${DESTDEVICE}p1 /mnttmp
mkdir -p /mnttmp/EFI/BOOT
cp /boot/loader.efi /mnttmp/EFI/BOOT/BOOTX64.efi
umount /mnttmp



echo ""
  # Option 1: align to 4K, ashift=12
  echo "# Align the Disks for 4K (ashift=12) and create the pool"
  gnop create -S 4096 /dev/gpt/$DISKNAME

  # Option 2: align to 8k, ashift=13
#echo "# Align the Disks for 8K (ashift=13) and create the pool"
#gnop create -S 8192 /dev/gpt/disk0

zpool create -d -f -o altroot=/mnt -o feature@lz4_compress=enabled -o 
cachefile=/var/tmp/zpool.cache $POOLNAME /dev/gpt/$DISKNAME.nop
zpool export $POOLNAME
gnop destroy /dev/gpt/$DISKNAME.nop

zpool import -o altroot=/mnt -o cachefile=/var/tmp/zpool.cache $POOLNAME

echo ""
echo "# Set the bootfs property and set options"
zpool set listsnapshots=on $POOLNAME

                 continue
         fi
         zfs send -v ${snapshots[$i]} | zfs recv -F ${destination[$i]}
