Hi, I tried to upgrade my own cloud in a Raspberry Pi 3 last week. It was working fine before the upgrade.
I did the backup for config and data as Owncloud documentation following the instructions in this link: https://doc.owncloud.org/server/10.0/admin_manual/maintenance/manual_upgrade.html
It was from 10.0.3 to 10.0.7.
After I download and extract the files and move to the own cloud folder, I started again apache2 server and find out that it was asking me again the admin user and password and database data. I tried to enter my last admin user and password but it told me that the user was already in use.
I think Im missing a step to charge again my admin data but I didn't find information about it.
Hope someone can help me
