+## Schema-Synchronisation
+
+### Problem: Schema-Drift
+
+Wenn neue Collections oder Globals auf DEV hinzugefügt werden, muss die PROD-Datenbank
+entsprechend aktualisiert werden. Besonders die `payload_locked_documents_rels` Tabelle
+benötigt für jede Collection eine eigene `*_id` Spalte.
+
+### Automatische Synchronisation (im Deploy-Script)
+
+Das Deploy-Script führt automatisch `drizzle-kit push` aus:
+
+```bash
+# Im deploy-production.sh:
+pnpm payload migrate                    # Payload-Migrationen
+pnpm exec drizzle-kit push --force     # Schema-Sync
+```
+
+### Manuelle Schema-Synchronisation
+
+```bash
+# Auf dem Server:
+cd ~/payload-cms
+
+# Dry-Run (zeigt was sich ändern würde)
+./scripts/sync-schema.sh --dry-run
+
+# Schema synchronisieren
+./scripts/sync-schema.sh
+
+# Oder mit --force für CI/Automation
+./scripts/sync-schema.sh --force
+```
+
+### Best Practices
+
+1. **Nach Collection-Änderungen:** `pnpm payload migrate:create` auf DEV ausführen
+2. **Migrations committen:** `git add src/migrations/`
+3. **Schema-Datei prüfen:** `src/payload-generated-schema.ts` sollte aktuell sein
+4. **Vor Deployment testen:** `./scripts/sync-schema.sh --dry-run` auf PROD
