Usually, it is much safer to just copy the storage file(s).
Export/Import is known to fail with ZClasses that inherit
from other ZClasses defined in a different product (which probably
is not your case).

This usually means that its class could not be imported.
Have a look at Zope's "ClassFactory" and check why it is unable
to import/load the ZClass.
