How do I export a full project to previous version, instead of having to export file by file?

I have a Simulink project in 2020a that runs and executes 2020a fine (where it was build), but I need to export and save on GitLab as a 2019a project and run on a separate computer. I am able to export and save the files that I believe are all I need and dependencies into a 2019a folder, but when I open and try to run I get many errors referencing files that were built in 2020a and not compatible (even if they aren't dependent on the Simulink model I am trying to run). Do I need to separately export each file or can I do the entire project (unfortunately there are about 300 files..).
