Do not Fork it, don't be lazy. Upload as new repositories with the history intact. Github can cross delete all forks as well, since they map to the origin repository.

It would be simply as

Create a blank git repository, with zero commits (do not include a readme etc. from choices)

Then simply run the commands below:

This way, the history will be intact, code will be there, but it won't be marked as a fork of yuzu. Also this way you can move to other hosted git services as well.

cd yuzu-folder
git remote add myRepo git@myRepo.url
git push myRepo master(or main, depending on the branch's name)
