Code Migration Planning with Claude Code: Build vs Buy Decision
A production playbook for code migration planning in cross-industry operations using Claude Code: build vs buy decision, run-scoped inputs, logs, typed results, and artifacts.
Audience: Engineering teams preparing framework or API migrations
The problem
Engineering teams preparing framework or API migrations need code migration planning to run repeatedly against repository snapshots, target docs, and compatibility notes. In cross-industry operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Compare the work required to operate code migration planning: sandbox lifecycle, provider credentials, input injection, logs, artifact delivery, retries, and result validation.
Tradeoffs and failure modes
Building gives total control; buying the runtime compresses the path to a customer-facing workflow. For code migration planning, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
Decision table
Build internally if you need bespoke infrastructure primitives.
Use Argo if you need code migration planning as a product workflow: inputs, Claude Code, logs, result JSON, and artifacts.
Use both if a specialized sandbox must sit behind a stable run contract.
