Code migrations can be complex and time-consuming, often requiring deep understanding of both the source and target languages or frameworks. Factory can significantly streamline this process by assisting with code analysis, conversion, and testing. This guide will walk you through how to effectively use Factory for code migration projects.

​
Getting Started

Before beginning your code migration project with Factory, ensure you have:
  1. Access to Factory
  2. Your source code ready for migration
  3. A clear understanding of your target language or framework
If you’re new to Factory, refer to our Quickstart Guide to set up your environment.

​
Importing Your Code

To leverage Factory’s full potential for code migrations, you need to provide it with your source code. Here’s how:

Codebase Search

Use Factory’s codebase search feature to pull relevant code snippets directly into your session.

Local File Sync

Open the codebase explorer and use local file sync to give Factory a comprehensive view of your project structure.

​
Code Migration Workflow with Factory

​
1. Project Analysis

Start by asking Factory to analyze your project structure and identify potential migration challenges:
1

Overview Request

Ask Factory for a high-level overview of your project:“I’ve uploaded our project files. Can you analyze the structure and provide an overview of the main components, dependencies, and potential challenges for migrating from [source language/framework] to [target language/framework]?”
2

Dependency Analysis

Request a detailed look at project dependencies:“Please identify all external libraries and dependencies used in the project. For each, can you suggest equivalent libraries or approaches in our target language/framework?”
3

Complexity Assessment

Ask Factory to assess the complexity of the migration:“Based on your analysis, can you rate the complexity of migrating each component on a scale of 1-5? Please explain your reasoning and highlight any parts that might require special attention.”

​
2. Migration Planning

Use Factory to help create a detailed migration plan:

​
3. Code Conversion

Leverage Factory’s code generation capabilities for the actual migration process:
1

Component Migration

Start with individual components:“Let’s begin with migrating the [component name]. Here’s the source code. Can you convert this to [target language/framework], maintaining the same functionality?”
2

Code Review

Ask Factory to explain its conversion process:“Can you walk me through the changes you made in this conversion? Why did you choose these specific implementations in the target language?”
3

Optimization

Request optimizations for the converted code:“Now that we have a working conversion, can you suggest any optimizations or improvements that leverage specific features of [target language/framework]?“

​
4. Testing and Validation

Use Factory to help ensure the migrated code functions correctly:

Best Practices for Code Migrations with Factory

  1. Start Small: Begin with smaller, less critical components to get familiar with the migration process before tackling core functionality.
  2. Maintain Consistency: Ask Factory to adhere to the coding standards and patterns of your target language/framework.
  3. Incremental Migration: For large projects, consider a gradual migration approach. Ask Factory how to set up a system where old and new code can coexist during the migration process.
  4. Continuous Validation: Regularly ask Factory to review migrated code for consistency and adherence to best practices in the target language/framework.
  5. Document Changes: Use Factory to help document significant changes, especially where the architecture or design patterns have been altered in the migration.
  6. Performance Comparison: After migration, ask Factory to help you set up performance tests to compare the migrated code against the original.
