Last version Turnkey Redmine, instal ISO. All works, and works good. But I want up to Re4.0.

In docs Update RedmineUpgrade I see:

2. Copy your database settings-file config/database.yml into the new config directory.

3a. Copy your base configuration settings-file config/configuration.yml into the new config directory.

But i cant find it files...I conect console root

cd

cd /var/www/redmine/config/

and see only "database.yml.example" and "configuration.yml.example"

help))
