Older SCORM files convert to HTML?

Hello to all you talented IDs in here,

I need your wisdom!

 

We have some older SCROM Exports, currently lying in an LMS. When I open the .story, my updated version of the program will alter the course in some kind of way (texts, boxes, scrollbars, pictures move etc.). I think, most here know the phenomenon.
We want to transfer the existing Projects into another Homepage and need them as HTML5 Exports. There are A LOT of them. So, open and upload them as HTML would take me a long time (because I have to search manually what have been altert and correct it).
So before I tackle that kind of sisyphus-task, I would like to know:
Is there a possibility to convert the existing SCORM exports to HTML5?

Thanks in advance.
