This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file,
mt-config.cgi, to customize the behavior of the system.
By default, the script that Movable Type uses for upgrading is called mt-upgrade.cgi. In some situations—for example, if you are running MT under mod_perl, or if your server requires that your Perl scripts have the extension .pl—you may need different names for these scripts. You can set the names that will be used throughout the default templates and Movable Type code by changing these values.
Default value: mt-upgrade.cgi
