Yes, that could be it. For FileStorage, I have used the following pattern as 
part of a generations script:

Of course, you would want to pack your database after that.

No, part of your migration from version to version is providing generation 
scripts. The Zope App server is responsible for updating its own 
classes/types, but you have to do it for your code. If the app server is not 
totally clean in updating, please let us know, since it is a bug.
