<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Library update interpreter is your friend.
Included your updated metamodel in the transformer (alongwith the old
metamodel). For sanity rename the old metamodel to <meta name>-old before
importing the updated one. Now, run the Library Update interpreter (icon looks
like an ‘ear muff’). Tell it the old metamodel name i.e. <meta name>-old,
and the new metamodel name (you just imported). It will redirect all your
references in the transformation rules to your new meta. Now you can delete the
old meta from your transformation without any lost references.</span></font></p>

before deleting the old meta.</span></font></p>

GME meta-models after I included them into a GReAT project. Of course, it is
possible to change the project, but it hasn't any effect on the included
project in GReAT. I see the possibility to include the current meta-model for
the second time and to delete the old model, but than I have to rewrite all the
transformation rules which is unfortunately tedious work.</span></font></p>
