@HonkingGoose can you double check that I caught every change?

[HonkingGoose]

Still checking the others, but we can fix this one now.

I can confirm we have migrated the changes that I made in my original PR: https://github.com/renovatebot/renovate/pull/10243/files

I don't think we edited it any further in the feat: v26 PR: https://github.com/renovatebot/renovate/pull/10995/files#diff-79c717b40c9bee60d2c9256ae4944499e287678a4880b0c457ecdd1b8e111466

But might be good to run a diff between these two somehow to confirm we didn't make any further changes????

[rarkins]

I'd prefer to merge this ASAP if it satisfies both our checks

[HonkingGoose]

I ran a diff between my original PR and the feat: v26 PR, and we didn't make any more edits to existing monorepos.

We did add new monorepos in the feat: v26 PR, but new monorepos don't need a migration, as they're new. 😄

I'd say we're good to merge now.

Hopefully you've found all. 😅
