Well, the *sneaky* way to do it would be a funky one-time mod to the 
object's __setstate__ method -- but I caution against excessive 
sneakiness as potentially very frustrating to get right.

My inclination would be to write a one time "search and replace" method 
which crawled the ZODB looking for such objects and replaced them with 
newer versions.
