# Migrating Configuration Files

Since the ISAPI modules changed their names, from php4xxx to php5xxx, you need to make some changes in the configuration files. There were also changes in the CLI and CGI filenames. Please refer to the corresponding section for more information.

Migrate the Apache configuration is extremely easy. See the example below to check the change you need to do:

Example B-4. Migrating Apache configuration files for PHP 5
    # change this line:
    LoadModule php4_module /php/sapi/php4apache2.dll

    # with this one:
    LoadModule php5_module /php/php5apache2.dll

If your webserver is running PHP in CGI mode, you should note that the CGI version has changed its name from `php.exe` to `php-cgi.exe`. In Apache, you should do something like this:

Example B-5. Migrating Apache configuration files for PHP 5, CGI mode
    # change this line:
    Action application/x-httpd-php "/php/php.exe"

    # with this one:
    Action application/x-httpd-php "/php/php-cgi.exe"

In other webservers you need to change either the CGI or the ISAPI module filenames.
