# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-4.2.x 4.2.x
# Navigate to the new working tree
cd .worktrees/backport-4.2.x
# Create a new branch
git switch --create backport-7596-to-4.2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 1b3427a254939a8a0c6ae32d27294f201bb06ca1,36ad5fc102f68e27666af38b871ff037d0935036,1ad0c2dec97d864c76f5d18c073c7bca9ed9fa57,cc2e34848ba87865bf0b3236f5dd6cf79f4cd845
# Push it to GitHub
git push --set-upstream origin backport-7596-to-4.2.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-4.2.x

Then, create a pull request where the base branch is 4.2.x and the compare/head branch is backport-7596-to-4.2.x.
