How to upgrade from 8.5.9 to 8.5.12?

Today I wanted to upgrade my CMS from version 8.5.9 to 8.5.12. But the dashboard only offers 9.1.3. That’s no option for me since my theme does not so support it. So I downloaded 8.5.12 und moved the concrete folder of the zip file to


as always, but the dashboard still does not offer me to update to 8.5.12. So far this always worked.

Can someone tell me what I am doing wrong?

Thanks Harald
