Your old object probably has a field that is not serializable. When an object is serialized, all of its non-transient fields are also serialized, and therefore these must be serializable as well.

And if you look at the error message more carefully, you will notice that it mentions the name of the class which was not serializable.
I agree. Here's the link:
subject: Only new Instance of object is serializable?
Java class consisting of serialVersionUID
Custom zip file- Object storage
write/read two byte arrays to single file- please help!
How the objects are constructed at the time of de-serialization?
