How can I save my model, with various library dependencies , build in Simulink 7.5 (R2010a) to an older version of Simulink?

I have a model build in Simulink 7.5 (R2010a). This model depends on many toolboxes as well as other customer libraries. I would like to save this model using "Save as" to a previous version of Simulink and run the same in previous version.

To save model with library dependencies to an older version of Simulink carry out the following:

1. Using model dependency viewer find dependent libraries

2. Save all the libraries and the model into older version of simulink.

One can automate this process using the command line version of the files dependencies. The automated script might look as follows

mdl = 'mymod';

load_system(mdl);

[files, missing, depfile, manifestfile] = ...

dependencies.fileDependencyAnalysis(mdl);

for i= 1:length(files)

      [pathstr, name, ext] = fileparts(files{i});

      if strcmp(ext,'.mdl')

      load_system(name)

      save_system(name, name, 'SaveAsVersion', 'R2007b');

      close_system(name,0)

      end

end
