Topcased if based on GMF and not on the UML metamodel therefore it is
impossible to recreate views from your existing model even if you upgrade
it. You can still try the model to model transformation but to get a
compatible GMF project from that, I doubt of it.
There is today a little split in the Eclipse modeling community between
modeling approaches and the use or not of GMF or EMF transformation stage.
I mean what is the best modeling approach and why do we model ?
Is-it important to spend time on the glue of GEF & EMF mapping or on Ecore
using EMF serialization for UML purposes ?
We have selected the second approach and I am persuaded that sooner or
later the market will adopt it.
The best model to model transformation is no transformation at all :-)
