to enhance my system a bit I started to upgrade my Raspberry pi 4 with an SSD instead of an SD Card. I tested the procedure on a testsystem upfront and it went fine with just one click on dietpi-dirve_manager transfer RootFS. So is went to my productive System and just did that.
Installed the SSD on an USB 3 Converter and went through the process via Drive_manager to transfer the ROOTFS.
After the reboot I realized that all folder inside /mnt/ are gone nothing there even on the SD Card.
Is there a solution to this topic already or any clues about that? Is there a way to save the database/installation of the Nextcloud (mysql in /var/lib/ is also broken) instance. The Nextcloud-User-Data isn’t gone, they have been on an external HDD.
