+# Migration Assessment - Executive Summary
+
+**Project**: ObjectQL Migration to @objectstack/runtime Architecture

+- 🔄 Components become plugins
+- 🔄 Plugin registration system
+
+**Type System**
+- 🔄 Use @objectstack/spec as base
+- 🔄 ObjectQL adds query-specific extensions only
+- 🔄 Remove duplicate definitions
+
+**Driver Interface**
+- 🔄 Implement @objectstack DriverInterface
+- 🔄 QueryAST translation layer
+- 🔄 Standardized driver protocol
+
+**Dependencies**
+- 🔄 @objectstack/* as peer dependencies
+- 🔄 Version alignment to 0.2.0

+
+## ⚠️ Risk Assessment
+
+| Risk | Impact | Probability | Mitigation |
+|------|--------|-------------|------------|
+| Breaking changes | HIGH | MEDIUM | Compatibility layer, migration tools |
+| Performance regression | MEDIUM | LOW | Comprehensive benchmarking |
+| Community resistance | MEDIUM | MEDIUM | Clear communication, support period |
+| API changes in @objectstack | HIGH | MEDIUM | Peer dependencies, version pinning |
+
+### Risk Mitigation Strategies
+
+1. **Backward Compatibility Layer**: Maintain v3.x API through wrapper
+2. **6-Month Support Period**: Continue v3.x maintenance
+3. **Migration Tools**: Automated migration assistance in CLI
+4. **Comprehensive Testing**: 100% test coverage maintained
+5. **Performance Benchmarking**: Ensure ≤5% regression
