# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/security-analytics-dashboards-plugin/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/security-analytics-dashboards-plugin/backport-2.x
# Create a new branch

# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 32e12d63edcfff98804d9a939c1fe731e5b37a31
# Push it to GitHub
git push --set-upstream origin backport-1063-to-2.x
# Go back to the original working tree
