Hi Compare-team,

How does the EMF Compare framework behave to changes, not only in the
model, but also in the Ecore model?

It is possible to compare models with not exactly the same Ecore model.
That's what the following option is for, right?
>compareOptions.put( MatchOptions.OPTION_DISTINCT_METAMODELS, new Boolean(
true ) );

So if I want to upgrade a customized model to a newer Version (with
changes in the model AND a changed Ecore model), would that be possible?
Is Emf compare able to merge changes into a model with an other metamodel?
Are conflicts between the models and metamodels detected?

So I have to load the models with the corresponding classes of the Ecore
model it was created from, I can not just load them with the newest
version of the Ecore model, right? That would mean, that I have to keep
all versions of the Ecore model or rather the generated Code in my project
in order to compare models of a changed Ecore model.

Thanks for carifying the case :)
