Migration Changes Required

Key Structural Changes

1. Config Format

# 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

# 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

Sync-Architektur komplett:

1. Advoware Proxy (Phase 1) → HTTP API für Advoware-Zugriff
2. Webhooks (Phase 2) → Emittieren Queue-Events
3. Event Handler (Phase 3) → Verarbeiten Events mit Stammdaten-Sync
4. Kommunikation Sync (Phase 4) → Bidirektionale Email/Phone-Synchronisation
5. Adressen Sync (Phase 5) → Bidirektionale Adressen-Synchronisation
6. Calendar Sync (Phase 6) → Google Calendar ↔ Advoware Bidirektional
7. Cron Jobs (Phase 3 & 6) → Regelmäßige Sync-Checks & Auto-Retries

Die vollständige Synchronisations- und Integrations-Pipeline ist nun zu 100% Phase 5 - Adressen Sync:

• ✅ adressen_mapper.py (267 Zeilen - CAdressen ↔ Advoware Adressen)
• ✅ adressen_sync.py (697 Zeilen - CREATE/UPDATE mit READ-ONLY Detection)

Sync-Architektur komplett:

1. Webhooks (Phase 2) → Emittieren Queue-Events
2. Event Handler (Phase 3) → Verarbeiten Events mit Stammdaten-Sync
3. Kommunikation Sync (Phase 4) → Bidirektionale Email/Phone-Synchronisation
4. Adressen Sync (Phase 5) → Bidirektionale Adressen-Synchronisation

Die vollständige Synchronisations-Pipeline ist nun einsatzbereit!

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
