!!!! Warning !!!!

Everything is fine up to now.
Next steps will write the flash and may be subject to failures.

It is highly recommended to perform a MTD backup and save the files
somewhere (USB device, PC)

    cat /dev/mtd0 > /tmp/mtd0.uboot.backup
    cat /dev/mtd1 > /tmp/mtd1.kernel.backup
    cat /dev/mtd2 > /tmp/mtd2.rootfs1.backup
    cat /dev/mtd3 > /tmp/mtd3.rootfs2.backup
    cat /dev/mtd4 > /tmp/mtd4.uboot-config.backup
    cat /dev/mtd5 > /tmp/mtd5.nas-config.backup
    fw_printenv -c /tmp/fw_env.config  > /tmp/uboot_config.backup.txt
    cd /tmp
    tar cvzf mtd_backup.tgz mtd?.*.backup uboot_config.backup.txt

    # now use scp / sftp to push/pull mtd_backup.tgz on another PC.

Be sure you will not cut the power until the end of operations.
In case of failure, you way need to recover with a Serial Console 
to run U-boot commands

    https://www.cyrius.com/debian/kirkwood/qnap/ts-219/serial/

Continue and flash the new partitions ? (y/N) y

[Flash 'NAS config' partition content (ie 'NAS config' + head of Kernel) (still a 'safe' op)]

[Change U-boot config with new values)]

[Flash tail of the kernel in old 'Kernel' Partition]

[Make a copy of /tmp/fw_env.config into /etc/fw_env.config (if not already existing)]

SUCCESS. 

Now, REBOOT !

Notes: 
- DO NOT PERFORM A KERNEL OR SYSTEM UPDATE before the next reboot !... 
  so don't wait too long.
- Consider compressing initrd with 'xz' to optimize the size with:

    echo "COMPRESS=xz" > /etc/initramfs-tools/conf.d/compress
