Yes, but the classes must not have gotten different names...

I can assure you that "__module_aliases__" works in principle
(I used it).

When "__module_aliases__" contains a pair "module_path, module",
then "sys.modules" is extended by

     sys.modules[module_path] = module


It might be necessary that "package_path" must have
an entry as well in "sys.modules" if "module_path" is
"package_path.module_name".


>Any other ideas?

Check that the "__module_alias__" works as expected:

  *  make an External Method

  *  import the class from its old place in the External Method

  *  see what exception you get

If you do not get an exception, the object should be loaded...
