## Breaking Changes

3 breaking change(s) detected:

| Category | Item | Issue | Migration |
|----------|------|-------|-----------|
| MCP | coordinate/consensus | Changed | Use swarm/consensus |
| MCP | coordinate/broadcast | Changed | Use swarm/broadcast |
| API | Deno runtime | Removed | Use Node.js 20+ |

## Migration Guide

### Quick Start

1. **Enable V2 Compatibility Mode**

```typescript
// In your V3 configuration
const server = createMCPServer({
  transport: 'stdio',
  compatibility: {
    v2: true,
    paramTranslation: true,
    deprecationWarnings: true
  }
});
```

### Code Examples

#### CLI Migration

```bash
# V2 (deprecated but supported)
npx claude-flow hive-mind init
npx claude-flow hive-mind status

# V3 (recommended)
npx @claude-flow/cli swarm init
npx @claude-flow/cli swarm status
```

#### MCP Tool Migration

```typescript
// V2 tool call
const agent = await mcp.callTool('dispatch_agent', {
  type: 'coder',
  name: 'my-agent',
  priority: 8
});

// V3 tool call (with compatibility layer)
const agent = await mcp.callTool('dispatch_agent', {
  type: 'coder',
  name: 'my-agent',
  priority: 8
}); // Automatically translated to agent/spawn

// V3 tool call (native)
const agent = await mcp.callTool('agent/spawn', {
  agentType: 'coder',
  id: 'my-agent',
  priority: 'high'
});
```

#### API Migration

```typescript
// V2 imports
import { HiveMind } from 'claude-flow/hive-mind';
import { MemoryManager } from 'claude-flow/memory';

// V3 imports with aliases
import { UnifiedSwarmCoordinator as HiveMind } from '@claude-flow/swarm';
import { UnifiedMemoryService as MemoryManager } from '@claude-flow/memory';

// Usage remains the same
const hive = new HiveMind();
await hive.initialize();
const agent = await hive.spawn('coder');
```

### Migration Scripts

#### Automatic Migration

```bash
# Run the V3 migration tool
npx @claude-flow/cli migrate --from v2 --to v3

# Migrate configuration
npx @claude-flow/cli migrate config --input .claude-flow/config.yaml

# Migrate memory database
npx @claude-flow/cli migrate memory --input .claude-flow/memory.db
```

#### Manual Configuration Migration

```yaml
# V2 Configuration (.claude-flow/config.yaml)
orchestrator:
  maxAgents: 10
  defaultStrategy: balanced
memory:
  backend: sqlite
  path: ./.claude-flow/memory.db
coordination:
  topology: hierarchical

# V3 Configuration (.claude-flow/config.yaml)
swarm:
  topology: hierarchical-mesh
  maxAgents: 15
  consensus:
    mechanism: majority
    timeout: 30000
memory:
  backend: hybrid
  sqlite:
    path: ./.claude-flow/memory.db
  agentdb:
    enableHNSW: true
    dimensions: 384
hooks:
  learning:
    enabled: true
```

## Recommendations

1. Enable V2 compatibility mode in MCP server configuration
2. Update tool calls to use new naming convention (e.g., agent/spawn)
3. Update import statements to use @claude-flow/* packages
4. Use provided import aliases for backward compatibility
5. Consider using tool name translation layer for gradual migration
6. Run migration script: npx @claude-flow/cli migrate
7. Update to Node.js 20+ (Deno support removed)

## Feature Compatibility Matrix

| Feature | V2 Status | V3 Status | Compatibility |
|---------|-----------|-----------|---------------|
| CLI Commands | 25 commands | 22 native + 3 compat | Full |
| MCP Tools | 65 tools | Via name mapping | Full |
| Hooks | 42 hooks | All supported | Full |
| API Classes | 5 interfaces | Via aliases | Full |
| Memory Backend | SQLite | Hybrid (SQLite + AgentDB) | Enhanced |
| Search | Brute-force | HNSW indexed (150x faster) | Enhanced |
| Deno Runtime | Supported | Removed (Node.js 20+) | Breaking |
