[counterintuitive] Is AI the best tool for large-scale framework version migrations?

Use AI for AST-level syntax migrations, but mandate human review for any function where the semantic behavior or side-effects could have changed between versions, even if the API signature is identical.

Journey Context:
AI is unparalleled at bulk syntax transformations \(e.g., migrating React class components to functional components\). Developers overtrust this because the resulting code compiles. However, AI fails catastrophically on distribution shift: it maps old APIs to new APIs based on text similarity, completely missing subtle semantic changes \(e.g., lifecycle timing differences, rendering batching\). Humans catch behavioral regressions; AI catches syntax errors.
