## Migration Changes Required

### Key Structural Changes

#### 1. Config Format
```python
# OLD
config = {
    "type": "api",  # or "event", "cron"
    "name": "StepName",
    "path": "/endpoint",
    "method": "GET",
    "cron": "0 5 * * *",
    "subscribes": ["topic"],
    "emits": ["other-topic"]
}

# NEW
from motia import http, queue, cron

config = {
    "name": "StepName",
    "flows": ["flow-name"],
    "triggers": [
        http("GET", "/endpoint")
        # or queue("topic", input=schema)
        # or cron("0 0 5 * * *")  # 6-field!
    ],
    "enqueues": ["other-topic"]
}
```

#### 2. Handler Signature
```python
# OLD - API
async def handler(req, context):
    body = req.get('body', {})
    await context.emit({"topic": "x", "data": {...}})
    return {"status": 200, "body": {...}}

# NEW - API
from motia import ApiRequest, ApiResponse, FlowContext

async def handler(request: ApiRequest, ctx: FlowContext) -> ApiResponse:
    body = request.body
    await ctx.enqueue({"topic": "x", "data": {...}})
    return ApiResponse(status=200, body={...})

# OLD - Event/Queue
async def handler(data, context):
    context.logger.info(data['field'])

# NEW - Queue
async def handler(input_data: dict, ctx: FlowContext):
    ctx.logger.info(input_data['field'])

# OLD - Cron
async def handler(context):
    context.logger.info("Running")

# NEW - Cron
async def handler(input_data: dict, ctx: FlowContext):
    ctx.logger.info("Running")
```

#### 3. Method Changes
- `context.emit()` → `ctx.enqueue()`
- `req.get('body')` → `request.body`
- `req.get('queryParams')` → `request.query_params`
- `req.get('pathParams')` → `request.path_params`
- `req.get('headers')` → `request.headers`
- Return dict → `ApiResponse` object

#### 4. Cron Format
- OLD: 5-field `"0 5 * * *"` (minute hour day month weekday)
- NEW: 6-field `"0 0 5 * * *"` (second minute hour day month weekday)

## Migration Strategy

### Phase 1: Simple Steps (Priority)
Start with simple API proxy steps as they're straightforward:
1. ✅ Example ticketing steps (already in new system)
2. ⏳ Advoware proxy steps (GET, POST, PUT, DELETE)
3. ⏳ Simple webhook handlers

### Phase 2: Complex Integration Steps
Steps with external dependencies:
4. ⏳ VMH sync steps (beteiligte, bankverbindungen)
5. ⏳ Calendar sync steps (most complex - Google Calendar + Redis + PostgreSQL)

### Phase 3: Supporting Infrastructure
- Migrate `services/` modules (advoware.py wrapper)
- Migrate `config.py` to use environment variables properly
- Update dependencies in `pyproject.toml`

### Dependencies to Review
From old `requirements.txt` and code analysis:
- `asyncpg` - PostgreSQL async driver
- `redis` - Redis client
- `google-api-python-client` - Google Calendar API
- `google-auth` - Google OAuth2
- `backoff` - Retry/backoff decorator
- `pytz` - Timezone handling
- `pydantic` - Already in new system
- `requests` / `aiohttp` - HTTP clients for Advoware API

## Notes
- Old system was Node.js + Python hybrid (Python steps as child processes)
- New system is pure Python (standalone SDK)
- No need for Node.js/npm anymore
- iii engine handles all infrastructure (queues, state, HTTP, cron)
- Console replaced Workbench
