title: Will deserialization overwrite the current object?
body: <p>What happens if I save (serialize) an object, modify unserialized object and then deserialize the object. Will a deserialized version of the object simply overwrite the modified one? Or do I have to delete existing object specifically (or do some other manipulations to ensure proper deserialization)?</p>
  
  <p><strong>PS</strong> Thank you for your replies. They really helped.</p>
