Code Migration

Overview

Migrate codebases between frameworks, languages, and API versions with automated, incremental transformations. This skill handles JavaScript-to-TypeScript conversions, framework upgrades, deprecated API replacements, and ORM migrations while preserving functionality and maintaining backward compatibility.

Instructions

When a user asks to migrate or modernize their code, follow these steps:

Step 1: Assess the migration scope

Analyze the codebase to understand:

• Source: Current framework/language version
• Target: Desired framework/language version
• Size: Number of files and lines affected
• Dependencies: Libraries that need updating or replacing
• Risk areas: Custom patches, monkey-patches, or framework internals usage
