update github gcc mirror forks to the new repo?

[Dennis Luehring]

so the github gcc mirror is already using the new reposurgeon based git
repo,

that means that all the commit hashes etc. are different if someone
forked this gcc mirror

so easy pulling from the mirror isn't possible anymore - or am im wrong?


is there any description how to "port" over github projects that
dependens on the old repo?

would a simple rebase work, or cherry picking?


thx
