Downgrade project with reference models and sub-models from 2023 to 2021

Hi all,

I have a project in matlab 2023 which contains a plenty of reference models and sub-models, it would not be nice downgrading all the models one by one, so I would like to downgrade the whole project from 2023 to 2021.

Does any of you knows a way to perform such a task with a script or anything like that?

Hi @Sergio Luiz Dutra,

I understand that you want to downgrade your project from R2023 to R2021.

1. In the Simulink window, File > Save > Previous version and save in your desired version. For more information, please refer to the Export Model to Previous Version of Simulink section in the following documentation link: https://www.mathworks.com/help/simulink/ug/save-models.html#f2-86382
2. Or You can use the "save_system" function to save your models in a format compatible with MATLAB 2021. Refer the following documentation to learn more about this function https://www.mathworks.com/help/simulink/slref/save_system.html#

Hope it helps!

Hello,

thanks a lot for your answer.

It works partially, I am still missing the data dictionaries in the exported version.

Do you know how to do it with the complete project package?
