What are the potential risks of changing the framework version in IIS for PHP applications?

Changing the framework version in IIS for PHP applications can potentially introduce compatibility issues with existing code and dependencies. It is important to thoroughly test the application after making any changes to ensure that all functionality is working correctly. 

<?php
// Sample PHP code snippet to check for compatibility with the new framework version
if (version_compare(PHP_VERSION, '7.4.0') < 0) {
    echo 'This application may not be compatible with the new framework version. Please test thoroughly before deploying.';
} else {
    echo 'Application is compatible with the new framework version.';
}
?>
