How can PHP version compatibility issues be resolved when migrating PHP files from one server to another?

PHP version compatibility issues can be resolved by updating the PHP code to adhere to the syntax and features supported by the new PHP version. This may involve changing deprecated functions, updating syntax, or modifying configuration settings. Additionally, using version control systems like Git can help track changes and ensure compatibility across different environments. 

// Example of updating deprecated functions
// Before
mysql_connect('localhost', 'username', 'password');
// After
mysqli_connect('localhost', 'username', 'password');
