My general approach would be this sequence of steps, let's assume his class is called Person in collection var name people.
If Person has an initialize method, rename it to initializeOld. Change superclass of Person to SDActiveRecord. Person warmUp. to setup the store for this new class. people do: [:e | e initialize ] to invoke active records initialize setting up it's necessary inst vars and marking all people as new rename Person>>initializeOld back to Person>>initialize. people do: [:e | e save ]
Migration complete.
Thanks a lot Ramon, I add this to Pharocasts. Laurent

Bernat Romagosa has left a new comment on your post "SandstoneDb, simple ActiveRecord style persistence...":
I was trying to migrate a simple image-based persistence app into Sandstone, so I just recompiled my biz objects to be subclasses of SDActiveRecord, but of course the objects I want to save are already created and "floating" in the image, so when I try to save them I get an error as many instvars haven't been initialized upon creating these objects (as they were already there).
Is there a way to automatically do this?
Thanks!
Bernat.
