About migrate

Implementation migration — replace internal implementation while preserving external behavior. Covers framework swaps, technology upgrades, domain model evolution, and gradual language migration. Builds on the refactor skill large-scale process (decompose → identify scope → execute → verify) with coexistence, equivalence verification, and convention specification.

实现迁移 — 在保持外部行为不变的前提下替换内部实现。涵盖框架替换、技术升级、领域模型演进以及渐进式语言迁移。基于重构技能的大规模流程（分解 → 确定范围 → 执行 → 验证），并增加共存策略、等价性验证和约定规范。
