- Audit Current System: Use our analysis tools
- Set Clear Goals: Performance, maintainability, features?
- Plan Downtime: Most migrations require 2-8 hours
- Backup Everything: Create migration branch
- Follow Guide Step-by-Step: Don't skip steps
- Test Incrementally: Verify each component
- Monitor Performance: Benchmark before/after
- Document Changes: Track what was modified
- Performance Testing: Load test the new system
- Team Training: Ensure everyone understands changes
- Update Documentation: Reflect new architecture
- Plan Optimization: Leverage new framework features

from agentically_migration_tools import MigrationTester
tester = MigrationTester()
results = tester.compare_outputs(
original_framework="langchain",
migrated_framework="crewai",
test_cases=["test1.json", "test2.json"]
)
print(f"Accuracy: {results.accuracy}%")
print(f"Performance: {results.performance_delta}%")- All agents respond correctly
- Tools function as expected
- Memory/context preserved
- Error handling works
- Performance meets requirements
Most migrations result in cost savings:
| Migration | Avg Cost Change | Token Efficiency | Performance |
|---|---|---|---|
| LangChain → CrewAI | -23% | +15% | +18% |
| LangChain → LangGraph | -8% | +12% | +25% |
| OpenAI Assistants → CrewAI | -67% | +30% | +40% |
| Any → Open Source | -60% | Varies | Varies |
- Problem: "It's just changing imports, right?"
- Reality: Architecture differences require careful planning
- Solution: Use our complexity calculator first
- Problem: Assuming equivalent functionality
- Reality: Subtle behavior differences can break workflows
- Solution: Comprehensive testing at each step
- Problem: Direct port without leveraging new features
- Reality: Missing 30-50% of potential benefits
- Solution: Follow our optimization guides
