# Dependency and framework upgrade

Cursor listed outdated packages by upgrade difficulty, then upgraded them in stages, including Remix v2 to React Router v7 on a 42k-line site.

Result: The author upgraded kentcdodds.com across all dependency tiers, finishing a Remix v2 to React Router v7 migration with routing matching the original structure.

## How it was set up

Cursor (Composer 1.5) plus a long-running background agent for the big migration. The agent searched migration docs. The project's existing tests and docs guided the work.

## Worth knowing

The agent struggled with the routing convention change and needed a corrective prompt. Good existing tests and docs made it work.

## Prompt

```text
Upgrade us from [framework A] to [framework B]. Before doing this, look up relevant migration docs and upgrade guides. Check that our framework-specific dependencies work with the new version, and find alternatives if they do not. Replace patch files with [simpler approach].
```
