good, when you apply the changes on the image, you changes are
applying in all instance of your objects..if that modifications has
incompatible changes, (I can guess, change a simple instance by a
collection, or some thing like that), may be you needed do a script,
to make a intermediate state. and run that script by seaside object
inspector, by example.

In my case, when I work with pharo (in most cases), I use the
monticello's way. I don't have so much experince in gemstone, but
genstome has a object version's system and you need change the
instances structure explicitly
