## [Introduction] AgenticMigration: A Human-AI Collaborative Code Migration Workflow for Scientific Computing

### Project Basic Info
- Original Author/Maintainer: ssciwr (Scientific Software Center, Heidelberg University)
- Source Platform: GitHub
- Release Date: May 29, 2026

### Core Content
AgenticMigration is a human-AI collaborative code migration workflow for the scientific computing domain, specifically addressing migration issues of legacy code such as Fortran, C++, and old Python versions. Its core concept is "human-in-the-loop": AI handles repetitive migration tasks, while human experts are responsible for key decisions and quality control, balancing efficiency and quality, and enabling knowledge transfer and incremental migration.

## Project Background and Problem Definition

## Challenges of Legacy Code
Historical code in the scientific computing domain (Fortran, C++, early Python) faces:
- Difficulty leveraging modern resources due to hardware architecture evolution
- Security risks from discontinued dependency libraries
- Maintenance difficulties caused by original developers' departure

## Limitations of Traditional Migration
- **Manual Rewriting**: High cost, requiring scarce talent proficient in both old and new technologies
- **Fully Automated Tools**: Struggle to handle the complexity and domain-specificity of scientific code

AgenticMigration addresses this pain point by proposing a human-AI collaborative solution between fully manual and fully automated approaches.

## Core Concepts and Technical Architecture

### Core Concept: Human-in-the-Loop
Advantages include:
- Balance of efficiency and quality: AI handles standardized conversions; humans ensure correct migration of domain knowledge
- Risk control: Key decisions are reviewed by humans
- Knowledge transfer: Migration process is documented
- Incremental progress: Migrate in modules and phases

### Multi-Stage Migration Pipeline
1. **Code Analysis and Understanding**: Build code structure graphs, identify dependencies, data flows, and key algorithms
2. **Migration Strategy Planning**: AI generates proposal suggestions; humans review and adjust
3. **Code Conversion and Refactoring**: Syntax conversion, data structure modernization, test generation, etc.
4. **Validation and Testing**: Unit test comparison, performance benchmarking, numerical precision analysis
5. **Manual Review and Iteration**: Humans mark improvement points; AI iterates and optimizes

## Supported Migration Scenarios

### Fortran Code Modernization
- Fixed-form → free-form conversion
- Migration from old to modern Fortran standards
- Cross-language migration from Fortran to Python (NumPy/SciPy)
- OpenMP old syntax → new standard parallelization

### C++ Code Refactoring
- C++98/03 → C++17/20/23 standard upgrade
- Raw pointers → smart pointers conversion
- Simplification of template metaprogramming
- Dependency library update and replacement

### Python 2→3 Upgrade
- Syntax fixes (print statements, division, etc.)
- Standardization of string/byte processing
- Dependency library compatibility handling
- Integration of type annotation addition and checking

## Practical Application Value

### Digital Transformation of Research Institutions
- Protect research investments and avoid redundant development
- Adapt historical achievements to modern computing platforms
- Lower the threshold for young researchers to take over legacy code
- Promote open-source code collaboration

### Industrial Simulation Software Maintenance
- Extend the lifecycle of core algorithms
- Support migration to GPU/distributed computing
- Improve integration with modern tools
- Meet maintainability compliance requirements

### Open Source Scientific Computing Ecosystem Construction
- Give new life to classic algorithm libraries
- Lower the threshold for new contributors
- Promote cross-language tool integration

## Technical Challenges and Solutions

### Semantic Equivalence Guarantee
- Symbolic execution to compare key function logic
- Fuzz testing to generate large amounts of input for output validation
- Domain experts annotate precision-sensitive paths
- Layered incremental validation

### Performance Regression Prevention
- Performance profiling to guide optimization
- JIT compilation and vectorization suggestions
- Preserve C/Fortran in critical paths
- Redesign parallelization schemes

### Dependency Management Complexity
- Dependency graph visualization
- Alternative library recommendations
- Containerized deployment solutions
- Automatic virtual environment configuration

## Open Source Significance and Community Contributions

### Open Source Model Value
- Joint improvement by the global scientific research community
- Plugin mechanism supports discipline-specific needs
- Best practices spread quickly
- Lower the threshold for small teams to modernize code

### Project Significance
AgenticMigration demonstrates a new paradigm for human-AI collaboration to solve complex software engineering problems. As AI capabilities improve, this "AI handles patterned tasks + human decision-making" model will be applied in more fields.
