We are currently testing CDO features for future integration with our EMF based applications.

One thing we have stumbled upon is updating the models in the CDO package registry.
There are cases when we need to amend the model (like adding a new class or feature) and so far we could not figure out how to update it in case it was already registered.

Would be great if we could get some hints on the model update policy that we could follow further.

Thank you,
Radu.

Hi Radu,

Currently CDO does not support automatic model evolution or schema/instance migration, see:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=256856

The new backup/restore mechanism can help you a little bit:
