How can I migrate enumerated data types between data dictionaries?

I am rearchitecturing the data dictionaries (DD) of my model. the way that worked for me is opening each individual DD and use

exportToFile(sectionObj,fileName)

to export data to a .m file , then run all the files to load data into base workspace, and use the following command

importFromBaseWorkspace(myDictionaryObj, 'existingVarsAction','overwrite');

to import them into the new DD.

the mothod works fine for all data types except enumerted data type definitions (aka 'Simulink.data.dictionary.EnumTypeDefinition').

the question is a way to transfer the enumerted data type definitions between data dictionaries using a script (for reproduction)?

note I am using R2020b

I solved the problem by changing the medthod to iterating over all old DDs, fetching their entries and adding them to the new one while both source and destination DDs are open

allEntries = find(DataSecObj_source);
for j=1:length(allEntries)
    if ~exist(DataSecObj_destination,allEntries(j).Name)
        addEntry(DataSecObj_destination,allEntries(j).Name,getValue(allEntries(j)));
    end
end
saveChanges(mainDD_Obj)
Simulink.data.dictionary.closeAll(DDObj_source,'-discard')

this method transfer all the objects icluding enum data type defintions without the need for an intermediate stage of .m or .Mat files.

this seamed more intuitive but it did not work with me the first time so I thought about the other method mentioned in the question itself,m hopfully the thread is useful
