[Tutorial: How to access DSM's Data & System partitions]

It seems that does not work. A new install requires to format disks. There is no possibility to recover data partition by this way.

I modify my comment: only the system partition was formated. Data partitions were conserved when you erase the system partition. The reinstallation does not erase data.

Since no one answers me here I have taken the matter into my own hands. 

 

Tutorials are certainly all useful, but finally the easiest way is to delete the system partitions (2.4GB Linux RAID1 members: sda1, sdb1, sdc1, ... , sdx1) of all installed hard disks, if you have performed an update and the system is no longer bootable. Then simply use an unused synoboot.img and the system is migrated without touching the data partitions.

 

Disadvantage is that all installed apps, configurations and settings have to be reinstalled of course.

 

Thanks anyway for all the information written down here. Would only wish for the future that the community would answer a bit more active.
