git worktree add .worktrees/backport-2.0 2.0
# Navigate to the new working tree
cd .worktrees/backport-2.0
# Create a new branch
git switch --create backport/backport-2713-to-2.0
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 03bafe6ac66c7bd504a51bcd39ff204160d5e7c7
