Are there specific steps to follow when transitioning from an older PHP version to a newer one to ensure smooth operation of scripts and databases?

When transitioning from an older PHP version to a newer one, it is important to check for any deprecated functions or syntax that may cause issues with your scripts and databases. To ensure smooth operation, update your code to use the latest PHP features and standards. Additionally, make sure to test your scripts thoroughly after the update to catch any potential bugs or errors. 

// Example code snippet for updating deprecated functions in PHP
// Before updating
$oldArrayFunctions = array('array_merge', 'array_keys', 'array_values');
$newArrayFunctions = ['array_merge', 'array_keys', 'array_values'];

// After updating
$oldArrayFunctions = ['array_merge', 'array_keys', 'array_values'];
$newArrayFunctions = array_merge($oldArrayFunctions, ['new_function']);
