Code Migration

Definitions

1. The process of moving code from one language, framework, architecture, or execution model to another while preserving required behavior. Code migrations range from small targeted conversions to multi-quarter modernization efforts that must balance compatibility, testing, and incremental rollout.

   In plain English: Moving code from one technology or structure to another.

   Example: "The TypeScript code migration happened module by module so the team could keep shipping features instead of pausing the roadmap for a full rewrite."
