Full backup during update possible?

[domschmidt]

Hey there :)

i am about to update my mhi2 unit to the latest firmware version (MHI2_ER_VWG13_K4525_1_AIO_MU1367) soon.

I am scared of any sound related issues (I have a stock dynaudio system) and wonder whether the automatic install script can also do a full backup (not only a basic backup).

Do you have any hints? :)

Thanks in advance :)

I finally did it the following way:

1. installed M.I.B. first
   https://github.com/Mr-MIBonk/M.I.B._More-Incredible-Bash

2. did an advanced backup using M.I.B. (~40 min)

3. put the sd card back to the pc and copied all the sd card data to the pc (backup)

4. did a coding and adaptions backup using VCDS of device 5f (information electronics)

5. copied the AIO firmware to the sd card and installed the AIO firmware using recommended (autoinstall) way

All went good. No issues so far.

Thank you for your good job :)
