To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub.
git fetch
# Create new working tree.
git worktree add .worktrees/backport v12-branch
# Navigate to the new directory.
cd .worktrees/backport
# Cherry-pick all the commits of this pull request and resolve the likely conflicts.

# Create a new branch with these backported commits.
git checkout -b backport-519-to-v12-branch
# Push it to GitHub.
git push --set-upstream origin backport-519-to-v12-branch
# Go back to the original working tree.
cd ../..
# Delete the working tree.
git worktree remove .worktrees/backport

Then, create a pull request where the base branch is v12-branch and the compare/head branch is backport-519-to-v12-branch.

@jerico The back ports failed, and that's ok.

I made the same mistake last week. Stuff for v16-only which this upgrade guide is, doesn't need to back port to the older version branches. It may need merging to master if it didn't start there. But that's all.
