Deleting MT’s deprecated config files
mt.cfg
In Movable Type 3.2 we deprecated the use of mt.cfg as an official Movable Type configuration file. At that time we requested users to rename their mt.cfg file to mt-config.cgi.
Movable Type 4.0 drops support for the mt.cfg configuration file entirely. If you are still using mt.cfg, please rename it to mt-config.cgi before you begin your upgrade.
Use the mv command on the command line:
$ mv mt.cgf mt-config.cgi
mt-db-pass.cgi
If you’re using MySQL or PostgreSQL, move the content of the mt-db-pass.cgi file (which contains the database password) to the mt-config.cgi file using DBPassword Configuration Directives.
DBPassword mtpasswd
