Migration Process

Step 1: Audit Current Usage

1. Identify all imports/requires of the source framework
2. Map which features and APIs are used
3. Catalog plugins, middleware, and extensions in use
4. Count affected files and estimate scope

Step 2: Map Source to Target

For each source feature in use, determine:

Flag features with NO direct equivalent — these need custom solutions.

Step 3: Migration Plan

Create an ordered migration plan:

1. Setup: Install target framework alongside source (coexistence period)
2. Configuration: Migrate config files (build config, env, plugins)
3. Core: Migrate entry points and routing
4. Components/Modules: Migrate individual files (ordered by dependency — leaves first)
5. Tests: Update test setup and migrate test files
6. Cleanup: Remove source framework dependencies

Step 4: File-by-File Migration Order

List every file that needs changes, ordered by:

1. No dependencies on other migrated files (migrate first)
2. Shared utilities and types
3. Core modules
4. Feature modules
5. Entry points (migrate last)

Step 5: Execute Migration

For each file:

1. Show the current code
2. Show the migrated code
3. Explain what changed and why
4. Run tests after each file to catch regressions

Rules

• Migrate incrementally — one file or module at a time
• Keep both frameworks running during migration if possible
• Run tests after every change
• Don't change functionality during migration — only change the framework layer
• Flag any features that cannot be migrated 1:1
