I'm following instructions from here: https://docs.osticket.com/en/latest/Getting%20Started/Upgrade%20and%20Migration.html#uploading-files
Step 6: Do not overwrite your ost-config.php file (in the include directory) or else you will lose your MySQL admin settings.
Step 9: Once you’ve overwritten the files, rename config.php to ostconfig.php (config.php is found in root osTicket directory).
No config.php found in root directory. Is Step 9 still valid for 1.11?
