Adding methods and/or properties to an existing custom class

P: 4
I am coding an application in VB.Net 2005 where objects of a custom class are saved/retrieved into/out of a DB. As my application moves into its 2nd version I have to add new methods and properties into my custom class.

How does one go about adding new methods and/or properties to a custom class and then updating existing objects of that class w/out breaking everything?

Ex: Pull existing object from DB -> Convert to new version of object class -> Save back into DB

I've tried CTYPE, deep cloning, making an new class that inherits the old class, etc. All to no avail, and I can't seem to find the answer anywhere.

Any pointers in the right direction would be greatly appreciated.

Thanks!
