This is contemplated through the usage of class versioning.  See documentation.

  Hey,

    I have a class with a few data members that is serializable. Note that, I already have an archive ( test.txt ). Now, I want to serialize a couple more members. I went ahead and added the new members to my serialize functions. When I read from the archive ( test.txt ) , I get an exception. This is understandable, because the archive doesn't have the new members that I'm trying to read out. 

    My question is, is there a way to check for the existence of a member before deserializing an object from the archive ? 

  Thanks in advance, 
  Sandeep.
