Hmm, I won't quibble about "migration code". +1.

If the code which *used* to work using 'getToolByName' now breaks beofre
that step is done, then we have a problem.  If there is a clear, simple
step to perform after upgrade, then we should be OK.

E.g., we might tell folks to do something like:

 $ cd $INSTANCE_HOME
 $ ./bin/zopectl run Products/CMFCore/scripts/updateSites foo bar/baz

To upgrade the 'foo', and 'bar/baz' site objects.  I see no benefit to
trying to do any migration from within the ZMI here.
