How to migrate from 2.9.22 to later version without lost of configuration?

[admMarcMi]

Hello
For years I'm using Nginx without any issue (on docker on Synology) with Maria DB

I tried to do the upgrade to 2.10.x but:

• The admin account get reseted to the default
• I cannot see any of the rules and settings and certificates

if I downgrade to 2.9.22 all is there.

Any known issue I missed? any step I'm forgetting?
