XMI import does not overwrite model

[arne_m]

Hi,

I have a model in EA that was imported from C++ sources. Now I want to update it because the sources have changed externally, but I can not just synchronize.  So I have exported the new model as XMI and now want to import it in my project so that it overwrites the old model but keeps class references from other models. The problem is that the old model is not overwritten, but a new model is created that is lying in parallel to the old one in the project browser. The same thing happens when I try to import just a package. Is there a way to tell EA to overwrite the old model?
Thanks in advance!

Best regards,
Arne
