I’m responsible for migrating a large number of Miro boards to FigJam — it’s a big company with many, many boards :/
When exporting large boards with vector content, I run into issues on the Miro side due to their size. But the main reason I’m asking here is that I’m also facing problems in Figma: when importing large files, some content gets clipped and ends up outside the FigJam board, making it impossible to retrieve.

Of course, I could divide the exports into smaller sections, but I’m expected to finish this project before next decade :)
Is there any tips or recommendations on how to handle this in a more efficient way? Plugins? 

Thanks a lot!
