How to create a new repository from a specific commit?

Question

git

Please tell me how to create a new repository starting from a specific commit and migrate all branches.
Now state is
master - old
development code - first commit just deleted all files (ref XXX)
All other branches are from development
I want to make a new repository whose history starts from commit after ref XXX and drag all branches there (without current master)

Answer 1

what is the real task? master to delete on the server?
git push origin :master
old commits can be merged into one with a rebase if you're ashamed of the history ;)
